The characteristics and use of the stretch film
Introduced the equipment of Italian DOLCI company, and selected linear low density polyethylene (LLDPE) imported by DOLCI and other companies, and made by three-layer co-extrusion casting process. The maximum film width is 2100mm, the maximum film speed is 500m/min, and the film thickness is 15μm-50μm. It can cut various specifications online. Sticky to one side and sticky on both sides. Two series of manual winding film and machine wrapping film according to the purpose.
Using VLDPE (adhesive) and LLDPE as raw materials, the obtained wound film has the characteristics of good tensile property, strong retracting force, high transparency, good puncture resistance, self-adhesiveness and low unit consumption. Whether it is used for collective packaging of products or pallet packaging of goods, it can achieve moisture, dust, labor, efficiency and cost reduction.
By using a three-layer co-extrusion casting process, by adjusting the proportion and composition of the three-layer resin, the tensile strength, transparency, viscosity and rigidity of the wound film can be changed, and the needs of different users can be maximized. The film is widely used in the packaging of paper, can, chemical fiber, electronics, picture tube, food, medicine and other industries.
Q: What is the minimum order quantity for stretch film? Will it be high?
A: Don't worry, the stretch film of the regular specification has been typeset, so the order quantity will be lower. You need to know your specifications, and the order quantity of special specifications will be higher.
Q: What are the special specifications?
A: The stretched film needs to extend the core, the color is not black and other colors are transparent.
Q: How to transport and pack?
A: You can make 9 rolls of a box, 6 rolls of a box, 4 rolls of a box, 2 rolls of a box, 1 roll and a box, you need to see the specifications to determine. However, the machine stretch film is one roll and one case.
Q: What is the role of stretch film core?
Answer: The stretched film core is used to facilitate the use of stretched film. It can be used conveniently in stretch film and reduce the wear of stretched film.
This package is similar to a shrink film package in which a wrapping film wraps around a tray to wrap the objects on the tray, and then two hot grips seal the membranes at both ends. This earliest form of use, and thus the development of more packaging forms, full width packaging, this packaging requires a wide enough film to cover the tray, the shape of the tray is regular, so it is suitable for film thickness of 17 ~ 35μm manual Packaging This type of packaging is the simplest type of packaging. The film is mounted on a shelf or held by a hand, rotated by a tray or wrapped around a film. It is mainly used for repackaging after the packaged tray is damaged, and for ordinary tray packaging. The packaging speed is slow, and the suitable film thickness is 15-20 μm; the tray mechanical packaging is the most common and widest form of mechanical packaging, which is rotated by the tray or the film is rotated around the tray, and the wrapping film is fixed on the bracket to move up and down. This packaging capacity is very large, about 15 to 18 plates per hour. The suitable wrapping film is about 15 to 25 μm thick; the horizontal mechanical packaging is different from other packagings, and is wound around the article by a wrapping film, and is suitable for long cargo packaging such as carpets, sheets, fiberboards, profiled materials, and the like.
