Stretch wrap machines wrap loads and products vertically or horizontally by means of a roll of stretch film that protects and stabilises them.
Eopac Machinery contains other products and information you need, so please check it out.
Vertical stretch wrappers cover packages placed on pallets, while horizontal stretch wrappers also cover products such as boards, pipes, and sheets. We will talk more about this distinction later in this text (and in particular about automatic wrappers).
In both cases, the number of stretch film spins depends on the type of wrapper.
A Pieri automatic turntable stretch wrapper, for example, is a machine suitable for companies that have little warehouse space. By default, it provides six complete spins of final wrapping both at the top and at the bottom on the pallet end points, followed by a film tensioning phase.
The wrapping process takes place by means of a motorised carriage that brings the palletised load closer to the machine, followed by the descent of a hydraulic arm locking it. This triggers the table rotation, which can reach 30 p/h.
The spiral pitch (wrapping factor) is adjusted automatically and measured by the ratio between the speed of the carriage going upwards and the travel speed of the wrapper.
The companies that can obtain advantages from the purchase of stretch wrappers are those companies with a warehouse or those operating in the warehouse inventory management.
Without further ado, the purchase of a packaging machine is a good choice for:
The purchase of a wrapping machine should be well thought out, because its purchase price varies between € 5.000 and € 30.000.
In case you wish to call a salesperson to ask for advice, we suggest that you gather the following information:
There are many types of wrapping machines that use special films (usually, polyethylene is used).
The first possible distinction is between manual wrappers, semi-automatic wrappers – those present at airports for wrapping travelers’ suitcases – and automatic wrappers.
Please forgive us if we focus only on the latter, as we at Pieri are experts in automatic packaging machines.

The automatic wrappers are machines that do not require the intervention of an operator – they wrap the palletised load with a frequency of even a dozen pallets per hour.
A further distinction exists between horizontal automatic wrappers and vertical automatic wrappers.
The automatic vertical wrappers are useful for coating height-developed palletised products, products with reduced thickness or circumference; products that require an end to end wrapping.
The automatic horizontal wrappers, on the other hand, are used to wrap rectangular or square-shaped palletised products along their entire length.
Automatic vertical wrappers include:
Now that you have clearer ideas about the type of packaging machine you need, we want to list you some features that you need to consider for your next wrapping machine:
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.
