Product Details:

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.

 

How to calculate the required stretch film specifications?

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

high speed machine with stretch film

| 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.

machine stretch film

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).

  1. During the stretch machine rotation, the pre-stretching mechanism keeps the width of the stretch film while pulling the stretch film thin to reach the predetermined stretching ratio.
  2. During the rotation of the stretch machine, the puncture performance of the film remains the same as before stretching.
  3. If the stretch film narrows during the operation of the stretch machine, no matter how long the stretch film can be stretched, it will not be pre-stretched. This method has a low draw ratio (about 15% -20%), if the draw ratio exceeds 55% -60%, exceeding the film’s original yield point, the film becomes narrow, the puncture performance also loses, and the film is easy to break. And at a 60% tensile rate, the tensile force is also very large, for light goods, it is likely to make the goods deform.

What’s the difference between stretch film and Pre-stretch film?

  1.  If it is the same configuration as the stretch machine, the pre-tension stretch machine then the price of resistance to the pull stretch machine is higher.
  2.  The different drawing methods of stretch packaging equipment can be divided into“Pre-stretching” and“Resistance-stretching” two categories: pre-stretching under the same conditions as the“Resistance-stretching” save material. Resistance stretch machine resistance by resistance to stretch, the stretch film is generally 1:1, pre-stretch is in advance of the head of the stretch film has been drawn, the stretch film is 1:2.5-3, so”Pre-stretch” than”Resistance to stretch” save material.
  3. Stretch and wrap film is a packing method that stretches and tightly wraps elastic film around the package at room temperature and seals it at its end. Since stretch wrap does not require heat, the energy consumption is only 1/20 of shrink wrap. Stretch and wrap packaging can be used to bind and pack a single item, and can also be used for collective packaging such as pallet packaging, which can achieve the purpose of saving energy, reducing packaging costs, reducing transportation losses and improving logistics efficiency.
  4. The actual packaging area of the pre-stretch film is about 3 times that of the traditional wrap film in the market under the same weight low price, good quality, environmental protection and easy use. Compared with the stretch film, the cost saving is considerable. Moreover, the pre-stretch film is a high-strength pre-stretched single-sided adhesive stretch film, which is quite convenient to use and saves labor and money. The outer surface of the package is not easy to stick dust, clean and sanitary.
  5. The pre-stretch film with a thickness of 0.007mm(7μm) can achieve the stability and protection performance of conventional film packaging of 18~20μm. This product is a new technology product in China, compared with the traditional winding film, packaging the same goods, less consumption, and low cost! Prestretch film, is a new generation of green environmental protection prestretch films recently developed abroad. The product uses a new drawing process to make the original parent film lighter and thinner, but its physical tensile strength and wrapping force are basically unchanged. And no special packaging equipment, suitable for manual packaging, saving time, labor and money!

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.

 

Machine Stretch Film Advantages

  • Stretch film than shrink film saves raw materials and does not need a heat shrink packaging machine, thus saving energy.
  • With high strength, and high elasticity can be tightly wrapped in any geometric shape of the product, can prevent damage to the product, and has a good anti-loose, rain, and dust-proof effect. Proof and anti-theft effect.
  • High-strength machine-used stretch film is superior to ordinary machine-used film, that is, “Ultra-thin” and“High strength”, even if the film in a relatively thin case can also achieve a good packaging effect.
  • Ordinary machine stretch film can only meet part of the stretch film machine. For some of the higher requirements of the film machine, the common machine with the film will be easy to break the film, thus affecting the efficiency of packaging and the packaging effect. And high-strength machine stretch film will not appear this phenomenon.
  • Machine PE stretch film packaging with the use of enterprises to create great economic value. The former artificial way seriously hindered the development of enterprises, not only because slow packaging and quality can not guarantee, dragging down the development of enterprises. Now many enterprises are aware of the importance of modern equipment, and one after another adopt mechanized packaging.

Luggage Stretch Film

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.

 

What is nano stretch film?

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?
