Machine stretch film is the need to wrap film objects placed in the middle of the turntable, through the start of the turntable motor, drive the turntable rotation, and naturally wrapped film evenly in the surface of the object. The substrates now mainly consist of LLDPE, C 4, C 6, C 8 and metallocene PE (MPE).
The elevator motor also starts, driving the machine stretch film frame to move up and down, so as to achieve the machine stretch film in the object’s height direction.
Catering to the specific demand for securing bigger and heavier loads such as GRP Tanks, Motors, Cartons and Pallets; our Jumbo Rolls are much longer than regular Machine and Hand Grade Stretch Films. With gross weight being a maximum of 50 kg and a choice of widths ranging from 50 cm up to 150 cm in any single roll, this strong and durable stretch film is designed to meet the ever-challenging and ever-changing requirements of the logistics and warehousing industry.
The width of the scale calculation can be. | |
Weight Calculation Formula | Length Calculation Formula |
Length (m) * thickness (um) * width (cm) * 0.918=Weight | Weight(kg) / thickness (um)/ width (cm)/ 0.918=Length |
Give An Example | |
15 kg, 22μm, 50CM thick, about 1485m wide; | |
1525m, 20μm thick 50CM, wide about 14kg |
| 1. Thickness
The thickness of the machine-used stretch film is generally thick, the thickness of the ordinary stretch film is between 13μm and 22μm, and the thickness of machine-used stretch winding film is between 20μm and 35μm, the mechanical properties of the tensile stretch film will be improved with the increase of the thickness. We all know that if it is hand-packed items, we will wrap them according to the quality of the stretch film, for the poor quality will slow down the appropriate speed to complete the packaging work. The machine stretch film is a mechanically fixed file, self-running, stretch film mechanical performance can not meet the requirements of normal position, so in order to ensure the mechanical packaging, will correspondingly improve the quality of machine stretching winding film, increasing thickness is a proven method.
| 2. Draw ratio
We have all heard that the stretching rate of the tensile stretch film is between 200%-600%. As for the mechanical operation of the tensile winding film, there are additional requirements for the stretching rate. At present, the general requirement is 700%, which is a one-meter machine with a tensile stretch film that can stretch 7 meters without breaking.
| 3. Malleability
Ductility refers to the transverse tensile rate, the raw material of the film is linear particles, the longitudinal tensile strength is strong, and the transverse tensile strength is weak, which obviously can not meet the packaging needs.
Therefore, a suitable metallocene (other density polyethylene isomer) is added to the raw material, increasing the molecular weight per unit volume and strengthening the tensile force applied transversely.
The machine-used stretch film is used in the winding film machine. Stretch film machine is a kind of packaging machinery with an electrical device, that uses the tension of tensile film winding all kinds of bulk objects or whole objects, to package as a whole. According to the different structures, the stretch film machine is divided into pre-stretching stretch film machine and resistance stretching film machine.
Resistance stretch film machine refers to the film frame mechanical resistance mechanism through the friction resistance so that the film is passively pulled out of the speed to control the speed of the pallet goods rotation, the machine is wound onto the goods while the stretch film is pulled apart. Because the resistance can be adjusted to“Zero”, at the beginning of the packaging of goods, need to adjust the film speed, and stretch film in the packaging of the goods, film tightness is not adjustable, it can only be adjusted after the goods are packed. But for the lighter, higher goods or easy parts, its packaging cost is very high, stability is not as good as pre-stretching, manufacturers suggest that users choose a pre-stretching die frame to package better. Many users do not know the case, if the use of manual film to packaging, it is very easy to break the film.
Pre-stretch film machine refers to the power of the pre-stretch film frame mechanism, the machine with the stretch film arranged according to the pre-set“Stretch ratio”(up to 300%) after stretching the wound on the pallet goods. It is driven by the AC motor and two rubber-coated rollers, (pre-stretch more than resistance to stretch a frequency converter, AC motor), at any time the film speed is adjustable, the advantage is, even winding, the packing is beautiful and adaptable (it can be used for super-light, super-high or super-heavy goods).
Can also be made according to customer demand by printing stretch film with logo, color stretch film, anti-UV stretch film, etc., and packaging cartons and paper tubes can be customized according to requirements.

You might not think it, but wrapping several layers of luggage stretch film around a hard suitcase is the simplest physical defense for an international traveler.
Some terminals in Miami, Kennedy International Airport or Houston George Bush Intercontinental Airport Secure Wrap packers before security checks.
The machines, which pack nearly two million pieces of luggage a year, wrap them in luggage stretch film and turn them into mummies.
This is an industry where luggage packaging companies such as Secure Wrap, Seal & Go, TrueStar and others offer to Wrap luggage in multiple layers of Wrap. It only takes a minute to finish packing.
Luggage stretch film can prevent pricey suitcases from being scratched and soiled. After all, Skycaps are efficient, treat all cases equally when loading and unloading, and do not treat Louis Vuitton suitcases with affection. It also protects the suitcase from the saliva of the security dog. But the real bill people know is luggage stretch film packaging machine service is the biggest selling point theft.
According to the 2021 United States Department of Transportation Data, America tops the list with more than 1.9 million stolen or damaged luggage lost during travel. This was followed by Southwest Airlines, which reported more than 369,000 cases of improperly handled luggage.
It is precisely because of the tight luggage stretch film, open must leave a trace of the property, you carry the bag through the inspection, no one can slip any contraband into it while you are not paying attention.
Nano stretch film-full name is, nano-layer extrusion stretch film, 55 layers nano stretch film through nano-layer co-extrusion technology, 55 layers of film, a variety of materials (PP, PEO, etc.) composite layer extrusion molding, the single layer formed is a high strength and high toughness stretch film with a thickness of nanometer and a number of 55 layers.
55-layer nano stretch film advantages:
1, Compared with the common co-extruded film technology to produce a higher number of layers, generally in 2-17 layers;
2. The more layers, the better the physical and mechanical properties of the film material, mainly in the elongation, the geometric multiples of the increase, and can withstand a higher load and puncture strength;
3. Because of the problem of production technology, it is very difficult to achieve complete thickness uniformity, even in the extrusion process, discontinuous situation. And manufacturing costs are high. In addition, the material will have a high amount of oxygen intake (meaning that there may be invisible to the naked eye small bubbles) ;
4. The current advanced nano-film technology is 55 layers, an overall thickness of 12-20 microns, and the overall thickness is lower than the ordinary film.
55 layers of nano stretch film are made out of?
Our products are produced by the German company W & H, this year is the 150th anniversary of the establishment of W & H, which is a true sense of the centenary of the company, is the world-famous packaging equipment manufacturers, in casting/blowing film/printing/bag-making are in the world leading level.
55-layer nano stretch film is widely used
The 55-layer nano stretch film is suitable for all kinds of winding equipment, the higher the equipment configuration, the better the performance, suitable for high-speed ring winding machines, cantilever winding machines, single machines, manual and so on
55-layer nano stretch film cost-effective value
● use less material than the same year, save money!
● safer and stronger packaging;
● reducing equipment losses
● reduce membrane consumption and be more environmentally friendly.
