How Does Stretch Wrapping Work?

Most companies that produce, resell or store products are familiar with stretch film. It is used all over the world to store and secure products. How does stretch film work to secure and stabilize these products? What can be done for more effective load stabilization and packaging? In this article, we will answer these questions and offer tips and tricks to maximize efficiency and reduce costs when using stretch film.

To answer the question of how stretch film works, do we have to look at what the film is made of? The stretch film is made from lldpe (linear low density polyethylene). LLDPE is found in a wide variety of products, from trash bags to toys and containers. It is a desirable plastic for these products because of the flexibility it offers.

LLDPE stretch film is an ideal product for packing and securing loads due to its extensibility. The flexibility offered by LLDPE is the key to the functioning of stretch film. This extensibility provides increased resistance to tearing and puncturing as well as increased efficiency when applied correctly.

How Stretch Film Works?

Types of Stretch Film

The two basic types of stretch film are cast and blown stretch film. They are both made from LLDPE, but the process in which they are made differs.

Blown Stretch Film

The blown stretch film uses air during the production process. Air is blown into the film and used to cool the film. Blown stretch film is more expensive to produce, but offers better resistance to tearing and puncturing.

Cast stretch film

The cast stretch film uses rollers during the production process to cool the film. Cast stretch film is more affordable than blown film and suitable for most applications.

Cost Reduction

Because LLDPE is a petroleum-based product, stretch film manufacturers have taken great steps to reduce costs. Most of the new movies on the market are great options for cutting costs while securing charges. Manufacturers produce thinner, more resistant films that cost less and last longer. There are two specific drawbacks to the new thinner and stronger films.

Reduced Puncture Resistance

Because the new film is thinner, it often sacrifices puncture resistance. It is ideal and works very well with boxes and cases without sharp corners. When packing pallets and individual products with sharp corners, it can easily tear and tear during transport.

Reduced scalability

The new economical stretch film is stronger and more rigid than the traditionally calibrated stretch film. This rigidity reduces the amount of stretching of the film. This reduced stretch helps to reduce physical stress when applying the film, but decreases the tear resistance.

There are currently a wide variety of stretch film products. Each film has advantages and disadvantages. The two things to consider to know how stretch film works are stretch and puncture resistance. The heavier and sharper the packaged products, the more resistance to stretching and puncturing will be required. The objective is to achieve good puncture resistance and load stability at the most reasonable price. Call us if you have any questions or want to discuss the products we offer.
