Packaging film based on polyethylene with protective properties against infrared and ultraviolet radiation. A plasticizer has been added to the composition of the film for resistance to low temperatures and light-stabilizing additives that do not allow the film to break down when exposed to UV rays. The film has high strength, is made using triple extrusion (the film is welded from three layers with a perpendicular direction of the fibers in each layer). The latter property allows the film not to be damaged at the corners of the package and, therefore, not to spoil the appearance of the package.
A film with increased strength characteristics, consisting of a reinforcing high-strength polyethylene mesh, coated on both sides with low-density polyethylene developed using a unique technology and laminated up to 65 g/m² with kraft paper that protects wood from moisture, or without paper.
The film can be produced in two types:
- in rolls
- in the form of ready-made envelopes
Packaging of lumber with a film made in rolls is carried out by attaching the film to lumber with the help of paper clips using a stapler.
Envelopes can be made by:
- stitching on a sewing machine;
- welding with a heating element operating on a pulsed current.
Envelopes can be obtained from a film folded “in half” either in the form of a “cap” or in the form of a bag. Compared to packing lumber with film produced in rolls, the film savings will be: in the first case – 12%, in the second – 34%. Packaging film in the form of envelopes has another advantage – no additional costs for staplers and staples.
Film density basic 95 g/m², can be 75-140 g/m².
- maximum width per roll 3800 mm without logo
- 3700 mm with logo
- film quantity per roll 800-900 m²
- roll diameter 400-500 mm
- the length of the roll depends on the scheme of rolling the film into a roll
The film is folded into a roll either “twice”, or by partially bending the sides.
An anti-slip layer can be applied to the middle part of the film (up to 1200 mm wide).
For packaging in the summer, perforation is made on the side surfaces of the film (holes with a diameter of 0.1-1.0 mm, the distance between the holes is 20 mm). This waterproof perforation allows the bag to be ventilated and therefore protected from the greenhouse effect.
The film can be either one-color or two-color: the outer side is any color according to the Pantone standard (the basic version is white), the inner side is black.
On the field of the film it is possible to apply a logo according to the customer’s layout (any colors). The maximum possible dimensions of the logo: 1450x700mm – for one-color and 1200x700mm – for multi-color. The print quality is high. Utilization The film can be disposed of by burning in boiler furnaces, can be used for recycling.
Polypropylene protective film has good mechanical and physical properties. It perfectly protects objects made of wood and metals (aluminum, steel, etc.). The protective film helps to avoid corrosion, scratches, pollution.
The protective film will protect a variety of products: from technology to glass and building materials. It is used at enterprises for the production of building materials, at metal-rolling enterprises, etc. Films are especially needed to protect painted, laminated, polished and some other types of surfaces. They peel off easily and leave no marks on the surface. It protects cargo and goods from pollution and damage during transportation, storage, operation, etc., and thanks to it they are delivered to their destination in excellent condition. For example, a protective film reliably protects transport packages with lumber, which, during transportation, can be damaged by a damp environment or high humidity. Due to the properties of the film, products packed in it can stay in open areas for up to several months.
The protective film is divided into types depending on the adhesive layer: with a one-sided layer, with a double-sided one and without it at all. According to the color scheme, it can be black and white, transparent, color, tinted / reflective, mirror protective film.
