Stretch film, also known as pre stretch film and shrink wrap film, is the earliest PVC wrap film made in China with PVC as base material, DOA as plasticizer and self-adhesive function. Due to environmental problems, high cost (relative to PE, less packaging area per unit) and poor tensile property, PE tensile film was gradually eliminated when it was produced in China from 1994 to 1995. PE tensile film is EVA as self adhesive material, but it has high cost and taste. Then PIB and VLDPE are used as self adhesive materials. LLDPE is the main base material, including C4, C6,
Hand stretch film is used for the collective package or goods pallet package, which can prevent moisture, dust, reduce labor, improve efficiency, protect products and reduce costs. It is especially used for palletizing and transportation of goods. It can give full play to the strength, toughness and self-adhesive of the adhesive film, and cooperate with the tightening effect of layer by layer tension when winding, so as to achieve the best effect of palletizing.
Characteristics: lightweight, strong toughness, excellent puncture resistance, transparent and self-adhesive, etc;
Purpose: no matter it is used for collective package or goods pallet package, it can prevent moisture and dust, reduce labor, improve efficiency, protect products and reduce cost. It is especially used for palletizing and transportation of goods. It can give full play to the strength, toughness and self-adhesive of the adhesive film, and cooperate with the tightening effect of layer by layer tension when winding, so as to achieve the best effect of palletizing. A mechanical stretch film with professional semi-automatic, automatic stretch film machine use.
Stretch film Characteristics and used specifications: thickness: 15mic to 50 mic, width:250mm-1500mm, length: 500M-3000M

Large batch, wrapping machine generally in 15 ~ 80 pallets / hour.
1. Drag packaging: drag type winding machine is adopted, the drawing ratio is less than 200%, the stretching occurs between the film coils on the pallet, and the goods on the pallet drive the film coil to generate power on the film coil to adjust the tension.
2. Pre drawing packaging: pre drawing winding machine is used, which can reach 200% to 300% pre drawing. The film is stretched separately before wrapping the goods, so as to reduce the amount of film used for each pallet and make the goods more stable. Stretching occurs between two adjacent reels, and the stretching ratio is adjustable. Because the stretching process is between the two axes with very small spacing, the friction is large, the film is controlled, and the width is not narrow, which can reduce the material consumption.
