Principle and characteristics of PE stretch wound film

PE stretch wrap film can be called stretch film, stretch film, stretch wrap film and so on. With the help of the super-strength winding force of the stretched film, the product can be compactly bundled into a unit. And there are no sharp edges and stickiness. There is no looseness and separation of the product even in unfavorable environments.

Stretch film has the characteristics of strong toughness, high elasticity, tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, moisture and dust resistance, oil resistance, single-sided and double-sided adhesive. In use, it can save materials, labor, and time. In use, in order to make the stretch film tightly wrap the packaged items, the film needs to be stretched first, and then wrapped around the object. The stretch film has the following characteristics:

1. Strong tensile strength, not only has super tensile strength, but also has the ductility to resist impact.

2. The elongation is small and the tension can be maintained for a long time.

3. Strong temperature resistance, no deformation when used below 120 degrees.

4. Good flexibility, no sharp edges, safe operation, neither hands nor damage to the tied objects.

5. Low cost and high benefit.

With the help of the film's super winding force and retraction, the wrapping film compactly and fixedly bundles the product into a unit, so that the scattered small pieces become a whole, even in unfavorable environments, the product does not have any looseness or separation, and there is no Sharp edges and stickiness to avoid damage.

Primary protection: Primary protection provides the surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of dustproof, oilproof, moistureproof, waterproof and anti-theft.

It is particularly important that the stretch film packaging makes the packaged items evenly stressed, and avoids the uneven force from causing damage to the items, which cannot be achieved by traditional packaging methods (bundling, packing, tape, etc.).

Compression fixation: With the help of the retracting force of the stretch film, the product is wrapped and packaged to form a compact and space-free unit as a whole, so that the pallets of the product are tightly wrapped together, which can effectively prevent the product from being transported. The mutual dislocation and movement, and at the same time, the adjustable stretching force can make the hard products stick tightly and shrink the soft products, especially in the tobacco industry and the textile industry, which has a unique packaging effect.

Cost saving: The use of stretch film for product packaging can effectively reduce the cost of use. The use of stretch film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging quality.
