Stretch film packaging

Stretch film packaging

Stretch film packaging is similar to that shrink film packaging, film all around the pallet to pallet wrap, and two children to grasp both ends of the heat seal film together. Stretch films is the first use of the form, and thus the development of more packaging
Full width packing
Stretch film packaging requirements of this wide enough to cover the tray, tray shape rules, so has its use for Stretch film thickness of 17 ~ 35μm
Manual packaging
This package is the easiest stretch films packaging of a membrane mounted in a rack or by hand, rotate or stretch film from the tray turn around the tray. Mainly used in the wrapped tray damaged after the re-packaging, and general pallet packaging. This package is slow, for the stretch film thickness of 15 ~ 20μm;
packing around the machine pallet stretch fils
This is one of the most common form of the most widely used packaging machinery, by the pallet or pallet stretch films around the rotating tray rotation, stretch film can be fixed to the bracket up and down. The packaging capacity of large, about 15 to 18 per hour. The stretch film for about 15 ~ 25μm;
Horizontal packaging machine
Unlike other packaging materials turn around by the stretch film, packaging of goods for long, such as carpet, sheet metal, fiber, profile, etc.;
Paper tube packaging
LLDPE stretch film is one of the most recent use than old-fashioned paper tube packaging with pallet stretch films packaging better. For the stretch film thickness of 30 ~ 120μm;
Small items of packaging
This is the latest packaging stretch film, not only can reduce material consumption, but also can reduce the pallet storage space, in a foreign country, this package was originally introduced in 1984, just one year later, there were many on the market such as packaging, This packaging has great potential. For LLDPE stretch film thickness of 15 ~ 30μm;
Pipe and cable packaging
This is the stretch film in the field of application of a special example of the production line packaging equipment installed in the final, fully automatic stretch film instead of tape tied both materials, but also can play a protective role. Application of stretch film thickness of 15 ~ 30μm.
Stretch in the form of packaging tray body
stretch film packaging are subject to stretch, stretch pallet packaging machinery in the form of direct tension and pre-stretch. Pre-stretch is divided into two, one is pre-stretch rollers, a tension is electric. Direct tension is between the tray complete with stretch film stretch. This approach stretching ratio is low (about 15% to 20%), if the stretching ratio more than 55% to 60%, exceeding the yield point of the original stretch film, PE stretch film reduce the width of a puncture lost performance , pallet stretch films is easy to break. And in 60% of the stretch rate, the tension is still very great, for light goods, is likely to bring the deformation. Pre-stretch is completed by the two rollers. The two pre-stretch roller roller gear unit is linked together, stretch ratio can vary according to the gear ratio, tension generated by the turntable, the tension is generated within a short distance, roll and stretch film friction between force and large, wide indented so stretch film, pallet stretch films maintain the original puncture performance down. No stretching occurs when the actual wound, reducing the sharp edge or corner as result of the fracture, which can stretch the pre-stretch ratio increased to 110%. Power pre-stretch stretch stretch mechanism and the same pre-roll, two rolls is different from the power driven rotating tray stretch completely unrelated. So adaptable, light, heavy, no rules are applicable to the goods, the packaging when the tension is low, so this method is 300% pre-stretch ratio, significantly reducing material cost savings. For stretch film thickness of 15 ~ 24μm.
