If you are storing your films in a warehouse or area exposed to extreme heat, you will want to move your films to a cooler place that will not produce tacky films.
High temperatures may cause your film to melt or become tacky, causing your films to be problematic or unusable.
Suppose you are storing your stretch film in a facility that is subject to high temperatures during summer (or other times based on your location). In that case, you need to be aware of your storage protocols.
:
If you are storing your stretch films during the winter or in a place where the temperature is always cold, you will need to think about how you store your films and make some adjustments to the process.
Extreme cold can cause your stretch films to become brittle or crack. This may result in stretch films becoming unusable or even producing a safety hazard in relation to unstable loads.
If you are storing you films in a warehouse or area exposed to extreme cold, you will want to move your films to a warmer area that will not produce brittle films.
Suppose you do not have a warm enough space to prevent the adverse effects of cold temperatures on your films. In that case, you will want to consider implementing climate controls such as heating systems to control the temperature of your stretch film storage area.
Today, countless consumers demand that companies producing their favorite products "go green." Many companies are trying to source sustainable packaging to meet customer needs.
Additionally, many businesses are trying to source recyclable packaging materials in an attempt to meet consumer's sustainability demands.
One question we often get from customers is, "can you recycle stretch film?"
And the short answer is yes! However, while stretch film is recyclable, you cannot just throw the used film into a single-stream recycling bin.
Most single-stream and municipal recycling centers do not have the proper infrastructure to recycle stretch films.
But, specialized third-party stretch film recycling companies have the required infrastructure to recycle these materials.
And, some of these stretch film recycling companies will actually pay you for larger volumes of properly baled and sorted LLDPE used and waste film.
If you want to learn more about recycling stretch film and getting paid to do it, please reach out to one of our packaging specialists.
They will be able to help you find out if you can recycle your used stretch film and if you qualify to make a profit from doing so.
Many companies choose to wrap their pallets manually with hand stretch film. And this is a totally acceptable way to wrap pallets.
But, with an ongoing labor shortage, finding good laborers to work in your warehouse is not always easy. And even if you find the labor you need, you could be saving a lot of money by switching to automated stretch wrapping.
With an automated stretch wrapper, you can partially or fully automate your stretch wrapping.
With automated stretch wrapping, you can reduce the number of laborers in your warehouse, increase production speeds, improve safety, reduce film waste and save some serious coin.
But is automated stretch wrapping right for your business?
Depending on the number of laborers you can replace in conjunction with the volume of products you are wrapping, automated stretch wrapping may be able to save you a ton of money.
But how do you know if automated stretch wrapping is proper for you?
If you want to know if an automated stretch wrapper makes sense for your product palletizing and securing requirements, you will want to speak with a packaging expert.
They will help you understand how much a stretch wrapper costs, whether buying or leasing is the right choice, and how much cost savings you can reap from automating your stretch wrapping.
It should go without saying that when you choose to automate your stretch wrapping, that safety comes first.
Stretch wrappers are a form of industrial equipment that, if operated wrong, can lead to safety hazards. As such, it is imperative to educate yourself about stretch wrapper safety before purchasing, installing, and using an automated stretch wrapper.
Safety concerns that should be studied before implementation include the following items:
In an effort to provide you with the proper safety advice for automated stretch wrapping, we have compiled this guide to stretch wrapper safety that covers each of the bullet points above.
While stretch film is an excellent packaging material for palletizing and securing your loads, it may or may not be the suitable material for your needs.
Depending on what you are attempting to palletize, other materials may be better suited to your requirements (such as strapping).
To ensure transparency about using stretch film, as we suggest here, we need to note the most common problems with stretch film.
Reviewing these items will help you decide if stretch film is the correct packaging material for your business or if you should be using an alternative material such as strapping.
The most common problems with stretch film include:
In order to help you negate all of these issues, we have put together a guide to understanding each of these items.
This guide will help you understand if you can avoid these problems when palletizing your products and will also clarify whether stretch film is the right material for your needs.
After reading this guide, you should have everything you need to identify the proper type of stretch film for your stretch wrapping needs. But, you are probably wondering, where can you buy stretch film?
When it comes to purchasing stretch films, you have a few different options to choose from. Below, we will review the places where you can buy stretch film.
Online retailers are one option for buying stretch films. You can purchase stretch film from online retailers such as Uline, Amazon, or Ali Baba.
Shopping around for stretch film on online retailer's websites such as these may allow you to find the lowest price possible.
But, sellers on these sites often do not provide in-depth information on the materials, nor do they give access to packaging experts who can consult on whether or not you are purchasing the best film for your needs.
Your next option for buying stretch film would be brick-and-mortar retailers. You can purchase stretch film from department stores such as Home Depot, Lowes, and similar brick-and-mortar locations.
When buying from a store like this, you can physically and visually inspect the stretch film before you buy it.
And while these stores will have sales associates to help you in your buying process, they often do not have the expertise on stretch film to help you buy the proper material.

Your next option for purchasing stretch film is to buy direct from a stretch film manufacturer.
This is a popular choice for consumers as stretch film manufacturers are the premier experts on the brands of film that they manufacture.
Sales reps from stretch film manufacturers are some of the top thought leaders and experts on the stretch films that they sell.
The reps can answer any questions you may have about the films they offer and assist you in making a purchase.
With that being said, stretch film manufacturers only sell the brands of film that they make. As such, in many instances, they may try to sell you their brand of film regardless of whether or not it is the best film for your needs.
It is also essential to understand that not all stretch film manufacturing companies will sell directly to consumers. Some manufacturers only sell their films through packaging distributors.
Finally, we come to stretch film distributors. This is another popular option for many consumers when looking to buy stretch film for their company.
Stretch film distributors are brand agnostic. This means they source and sell multiple brands of stretch film under one roof.
Because stretch film distributors sell multiple brands of stretch film, their sales professionals will help you buy the correct film for your needs.
Stretch film distributors feature knowledgeable packaging experts who can review several brands of film with you to help identify the perfect film choice for your product, budget, and logistics requirements.
We should point out that Industrial packaging is a stretch film distributor. We offer some of the best brands of stretch film on the market today.
If you are interested in purchasing the stretch film that is most appropriate for your product palletizing needs, feel free to reach out to one of our packaging specialists today!
Imagine this: the average semi-truck (72') can fit 26 standard pallets inside it, without stacking. A single standard pallet can carry up to 4,600 lbs of cargo. That means just under 120,000 lbs of cargo can fit inside a semi-truck.
If it weren't for industrial stretch wrap, it's safe to say that much of that cargo would be tossed around, torn up, or shattered by the time the shipping container reached its destination. Stretch wrap plays an incredibly important role in the transportation industry, but what is it?
If you want answers, look no further! We've put together this introductory article on all things stretch wrap.
What is Stretch Wrap?
Not to be confused with saran wrap, stretch wrap goes by many names; stretch film, plastic stretch wrap, and industrial stretch wrap are some of the more common ones.
As its name implies, stretch wrap is a highly stretchable plastic film. Its primary function is to unitize loads, though it has several secondary functions that we'll go over in this article.
Check out this article's accompanying video to watch one of our packaging directors demonstrate the use and efficacy of several different types of stretch wrap!
What is Stretch Wrap Made Of?
First things first, what is stretch wrap made of?
Industrial stretch wrap is made from linear low-density polyethylene (LLDPE). While other types of polyethylene can be used, LLDPE is the most common material because of its elongation at break and puncture resistance.
Those are some big terms, I know. But what it really means is that a special type of plastic is used in the making of stretch wrap so that the product can have a high elastic recovery, which is ultimately useful for wrapping and holding large loads together.
What is Stretch Wrap Used For?
As mentioned earlier in the article, stretch wrap's primary function is to secure products together so that the loads don't fall over in transit. More often than not, this means securing products or materials to a pallet so that they can be shipped without damaging the load, or any other materials being shipped with the load.
All it takes is a basic layer of industrial stretch wrap to a load to a standard pallet. Its low cost and high efficacy have made industrial plastic wrap a staple of the shipping and transit industry. More than just a load stabilizer, though, stretch wrap has several secondary functions.
One of its many benefits is how it helps to reduce product loss. Industrial plastic wrap is very stretchy. Its elasticity allows the plastic stretch wrap to apply pressure to whatever it is securing when it's wrapped around a load, keeping things in place. Because of this, fewer items fall off pallets and go missing in transit.
It's for that same reason that industrial stretch wrap improves the stability of packages and the efficiency of handling and storing loads while decreasing the risk of injury for workers.
When looking at different varieties of stretch wrap, there are a host of added benefits, from UV protection, to color-coding. We'll cover all that later in the article.
How is Stretch Wrap Made & Why Does it Matter?
There are two main processes by which plastic stretch wrap is created, the first is cast extrusion, and the second is blown extrusion.
Let's break down the difference between these two extrusion processes.
Cast vs Blown Stretch Wrap?
Let's start with cast stretch wrap. Cast stretch wrap is made by a process called cast extrusion. In this process, plastic material is heated up and continuously melted into a flat die slot so that it can be pushed out onto a cooled roller, causing it to re-solidify in a new shape.
This process boasts a handful of benefits, like clearer transparency, ease of use for stretching, a good grip with two-sided cling, and less noise when stretching. Due to reduced manufacturing costs, cast stretch wrap is also more affordable to produce, making it a popular option over blown stretch wrap.
In a similar process to cast stretch wrap, the blown extrusion process begins by melting plastic material and pushing it through a die slot; imagine funneling hot, melted plastic through a tube and onto a flat, chilled surface so that it cools as a thin sheet.
Where blown extrusion differs from cast extrusion is that the die slot is ring-shaped, and the plastic is pushed through vertically to form a refined tube. Then, air is blown through an opening in the center of the die, causing the tube to expand like a balloon. From the top, cool air is blown onto the tube, chilling the plastic.
This process creates a tougher, yet more flexible stretch wrap. On top of that, blown stretch wrap has a high degree of memory once stretched, leading to more secure loads. Its superior memory, strength, and tear resistance make it an effective option over cast stretch wrap. Blown stretch wrap however is more expensive than cast stretch wrap.
Whether you should be using blown or cast stretch wrap should be determined by weighing out the benefits of each to see which is more applicable to your operation.
Blown extrusion produces a higher cling quality, but the cost of production is also higher because it produces more film per hour than cast extrusion. The blown extrusion process is also less consistent, leading to a less consistent product.
Cast extrusion is a faster process that produces a more consistent product that has better performance characteristics. While the cling quality is not as good as blown stretch wrap, this is offset by a quicker and more cost-effective production.
At the end of the day though, both of these products are viable for securing loads to pallets.
What Are the Different Types of Stretch Wrap?
Industrial stretch wrap comes in many varieties, each with its own use. When stretch wrap has a specific use, other than to unitize loads, it's referred to as specialty stretch wrap. Here, we'll review some of the most common specialty stretch wraps.
Pre-Stretch Wrap
Advantages: Pre-stretch wrap is just stretch wrap, but stretched up to 90% of its maximum stretch rate. This means it requires less stretching during the application process, which translates to about 50% less film consumption than other industrial stretch wraps.
Disadvantages: Because it is already stretched out, this film is thinner than your standard stretch wrap, meaning it has poor puncture resistance. In large or uneven loads where there are multiple corners, that can mean multiple punctures.
Use Case: If you're looking to increase cost-effectiveness without sacrificing quality, pre-stretch wrap is your go to. Because it uses about 50% less film, it can lead to huge cost savings.
UV Stretch Wrap
Advantages: Ultraviolet (UV) stretch wrap helps to protect the integrity of the stretch wrap from harmful UV rays by preventing photodegradation, a process by which rays of sunlight and the air can cause particles to degrade, damaging the stretch wrap.
Disadvantages: UV stretch wrap has two distinct disadvantages. The first is that it is more expensive than standard stretch wrap, owing to the film's special chemical makeup. The second is that it is made to order, which usually takes about a month to get to your business.
Use Case: If you're wrapping or storing loads outdoors, especially for extended periods of time, and want to avoid the stretch wrap degrading, then UV stretch wrap is the way to go.
Vented Stretch Wrap
Advantages: Vented stretch wrap allows products being contained by the wrap to get fresh air flow. This is particularly effective at creating the proper ventilation for produce to breathe so that it can ripen during transportation, though it is also used for meat, frozen foods, and plants.
Disadvantages: This stretch wrap has holes all over it, making it far easier to see what is being carried than other types of stretch wrap. It also has less strength than standard stretch wrap. This is because there is less plastic in it as a result of being covered in holes.
Use Case: If you ship produce that needs to breathe, especially for the purpose of ripening, this variety of stretch wrap is the best option.
Anti-Static Stretch Wrap
Advantages: A special additive that is applied to anti-static stretch wrap eliminates the possibility for this film to experience an electrostatic discharge. It clings tightly to itself for added security and reduces the amount of generated static compared to normal stretch wrap.
Disadvantages: Anti-static stretch wrap is typically thicker than your standard stretch wrap. This can be a problem if you need to see through the stretch wrap, as the added thickness can cause increased opaqueness. There is also the problem of limited manufacturing because it is more expensive.
Use Case: Anti-static stretch wrap is great for shipping electronics, electrical equipment, or anything flammable when you don't want to risk the chance of a static shock.
Colored Stretch Wrap
Advantages: The use of colored stretch wrap is for any facility that needs to easily separate shipments. The USDA, for example, only uses blue stretch wrap so that it is easy to identify if it gets in any food. It can be used as a means of color-coding, both during shipping and in storage. It is also designed to be puncture resistant.
Disadvantages: Colored stretch wrap can make it more difficult to see exactly what products or materials are secured to the pallet. This can make it a problem if transportation workers need to know what is in the load they're transporting. It is also made to order, meaning that if the manufacturer doesn't already have a batch in stock, it can take a long time to be produced and delivered to your business.
Use Case: Colored stretch wrap is useful for everything from warehouse color coding to inventory dating. Create a system of organization, implement it, and watch as the efficiency of your shipping and storage increases.
Coreless Stretch Wrap
Advantages: Coreless stretch wrap is more sustainable than regular stretch wrap because it does without the core, leaving nothing to be thrown out after all the stretch wrap is used up. Pair with a reusable core for more efficiency. In addition, it will always come pre-stretched.
Disadvantages: Coreless stretch wrap is the exact same as pre-stretch wrap, just without the core. Other than having no core, it has no advantages or disadvantages over pre-stretch wrap.
Use Case: If you're looking for a fully green manufacturing plan, or wish to promote sustainability at your business, coreless stretch wrap is the way to go.
Biodegradable Stretch Wrap
Advantages: Biodegradable stretch wrap is one of the newest stretch wrap variants out there. It is not only fully recyclable, but it is also biodegradable. So, while you may recycle it, the film will fully degrade in a landfill in approximately two years. It can break down in water or on land and breaks down so fully that it can be consumed by living organisms.
Disadvantages: This stretch wrap is soft, meaning that it has low tear resistance compared to standard stretch wrap. This affects its ability to maintain the security of an especially heavy load in transit.
Stretch wrap is an integral tool in load unitization, transportation, and storage. While it is essential to the structural safety of loads, it also provides an array of bonus benefits when taking full advantage of the wide selection of specialty plastic stretch wraps. Whatever the type of transportation or storage, there is a variety of stretch wrap that can help you in more ways than one.
