Polyethylene film
(1) Packaging adaptable polyethylene has large impact strength and low price. The heat-sealed part after processing has high strength and less breakage, so it is often used for transportation and packaging, but its gloss and transparency are not as good as PVC, in the heat shrinkage channel. Once expanded, it can be shrunk, and the appropriate shrinkage temperature is also 20 to 50 ° C higher than PVC. For these reasons, it is preferable to equip an air-cooling device after the heat shrink tunnel.
(2) Application examples Polyethylene shrink packaging should be applied to countless product packaging such as fresh food, vegetables, printed laminates, aluminum sheets, refractory bricks, fabric rolls, window cabinets, and cardboard.
The following is an example of fabric roll packaging and department store packaging.
Fabric roll packaging, because of the variety of fabric rolls, batch numbers, and multi-variety production, it is difficult to mechanize the packaging operation, but it is possible to realize the mechanization of the fabric roll packaging by shrink packaging. The packaging method is to supply the fabric roll, which is wrapped with polyethylene from top to bottom, and then sealed by A and B packaging sealing machine, and then through the heat shrinkage passage, so that the packaging polyethylene film will tightly Stick to the product and complete the packaging. It has the following characteristics: 1 can be packaged in any size; 2 high efficiency, when packaged by hand, two groups can only pack 100 rolls per hour, and shrink packaging can increase efficiency by 3-6 times; 3 perfect protection goods ; 4 packaging close to the fabric, its pattern, color will not change after packaging through the film, the shrink film is soft, will not wrinkle the fabric roll, can maintain the style of the original fabric.
The packaging of department stores is to save the holiday gift packaging from manual to shrink packaging, and achieve the goal of saving effort. After the packaging center is concentrated and shrinked, the subcontracting is sent to the society.
