Is there a difference between a stretch film and a protective film?

In fact, plastic wrap is a kind of stretch film, but because it does not need to have such high self-adhesive properties as stretch film, the amount of polyisobutylene used will be less, and polyisobutylene is mainly used to increase product flexibility and self-adhesiveness. Cling film is a kind of plastic packaging products commonly used by people to keep fresh food, and the main cling wrap on the market is: the first is polyethylene, which is mainly used for food packaging, such as fruits, vegetables, etc., including semi-finished products purchased in supermarkets are used with this material.

Got it? Some of the information is taken from the articles published by Pudi.

Stretch film, is LDPE through the blow molding machine directly blow molding, its stretch is relatively large, the general stretch film stretch ratio can be 300%-500%, and the stretch film is widely used, the normal is to wrap several layers of stretch film after the goods are packed before shipment, to prevent scratching the packaging or something.

The protective film, after the blow molding machine, plus the glue machine, coated with solvent-based glue, is generally pasted on the surface of the product to prevent scratches during transportation, install and stain the product, affect the aesthetics of the product, and the building board is widely used.

The most vivid stretch film is plastic wrap.

The most typical protective film is the mobile phone film, as well as the adhesive film on various shells.

Not a professional user, I know that this is pretty much the same.

Protective film: I don't know what kind of film you are referring to? Stretch film is mainly used to secure goods, so as long as the ductility and durability are good enough, there is no need to consider how it will harm the human body after heating (compared to plastic wrap).

Stretch film and plastic wrap.

The difference: Stretch film is used to wrap things. Supermarkets often use stretch film, such as punching a pallet of goods, and then you have to wrap the goods whole with stretch film. In this way, when the goods are pulled by forklifts, they will not be scattered. Otherwise, as soon as the goods are pulled, they will all be poured.

Plastic wrap is used to wrap around food, such as eating leftovers, and wrapping it on a plate. Put it in the refrigerator to keep it fresh, and there are fruits, you can also use plastic wrap. Mainly refers to food.

One is an industrial material, and the other is a food-grade material!

Plastic wrap is a type of stretch film, but because it does not require as high self-adhesive properties as stretch film, the amount of polyisobutylene used will be less, and polyisobutylene is mainly used to increase the flexibility and self-adhesion of the product. When the stretch film is used, it can use the self-adhesive elasticity of the film itself to stretch and wrap the goods, and rely on the viscoelasticity of the surface of the film to wrap the goods tightly with the tensile tension used during use, so as to achieve the purpose of protecting the goods.

The difference between PE protective film and PE stretch film is???

Hello dear, thank you for waiting, I will answer for you, the raw materials are similar, the processing technology is completely different: PE winding film is made of polyethylene plastic, polyethylene plastic is flexible, not easy to be ground by the general plastic crusher raw materials, and the specific raw material of PE cling film is also polyethylene, polyethylene is made according to the polymerization reaction. PE plastic wrap can be divided into various types according to the different raw materials and plasticizers used, and is mainly used in different types of places.

We hope you are satisfied.

There are a variety of materials such as PE PET OPP, etc., which are mainly used in the manufacturing process and the shipment of finished products, and play the role of protective film; The stretch film is made of PE material, which is a very thin film with high tensile strength, which is used for packaging, like this logistics freight express company, which is used for packaging; The composite film is composed of several materials, such as PE and PET synthesis, which is stronger than the general PE temperature resistance.

PE Breathable Film:

The breathable membrane in various fields of human life contains a large proportion of ultra-fine density inorganic filler, which is treated by casting micro-embossing and stretching process to form micropores, and the density of microporous distribution is large, so that the breathable membrane has a high moisture permeability, and only permeates gas without leaking liquid. It is a new material that has developed rapidly in the world, known as a breathable film, and is widely used in various fields of human beings because of its breathable but impermeable properties. Such as personal care field, clothing and textile field, medical and health field, agricultural field, food packaging and other construction, packaging, outdoor equipment and other fields.

Characteristics of PE film:

For non-breathable membranes, it has the following properties:

1.Superior air permeability with superior uniform air permeability effectively isolates moisture and expels heat and moisture.

2.More skin-friendly softness with an excellent hand feel, making the product more soft and comfortable.

3.Optimal physical and mechanical properties: excellent tensile and elongation properties.

4.PE has good chemical resistance, is not easy to corrode, and is difficult to print.

Classification of PE film:

PE material is polyethylene, which is the largest variety of plastic materials, and it is a polymer material synthesized from polyethylene. It is basically divided into two categories: low-density polyethylene LDPE; High-density polyethylene.

The materials are divided into five grades according to internationally uniform standards: PE32, PE40, PE63, PE80 and PE100. The production of PE pipes for water supply pipelines is high-density polyethylene HDPE, and its grade is PE80, PE100 and the MRS of PE80 reaches 8MPa; The MRS of PE100 is achieved to refer to the circumferential tensile stress strength of the pipe.

PE is a typical crystalline polymer. There are many types of it, commonly used are LDPE and HDPE, which are translucent plastics with low strength and a specific gravity smaller than water). LDPE is softer, (commonly known as soft rubber) HDPE is commonly known as hard soft rubber, it is harder than LDPE, poor light transmittance, and has a large crystallinity.

Hello, Fengzhao Technology protective film manufacturers serve you!

Saran Wrap. It is a type of stretch film, but since it does not require as high self-adhesive properties as stretch film, the amount of polyisobutylene will be less, and polyisobutylene is mainly used to increase the flexibility of the product.

and self-adhesiveness. Cling film is a kind of plastic packaging products commonly used by people to keep food, and the main cling wrap on the market is: the first is polyethylene.

This material is mainly used for food packaging, such as fruits, vegetables, etc., including semi-finished products purchased in supermarkets;

The second type is called polyvinyl chloride.

This material can also be used in food packaging ; The third is polyvinylidene chloride, which is mainly used for the packaging of some cooked foods. Due to the plasticizers used in PVC plastic wrap.

has a carcinogenic effect, and the production cost of PVDC.

It is too high, so most of the domestic plastic wrap tends to use PE as a raw material.

Stretch film, also known as stretch film, heat shrinkable film, is the earliest in China to use PVC as the base material, DOA as a plasticizer and self-adhesive production of PVC stretch film. Due to environmental protection problems, high cost (relatively large proportion of PE, less unit packaging area), poor stretchability and other reasons, when the domestic production of PE stretch film began in 1994 and 1995, it was gradually eliminated. PE stretch film first used EVA as a self-adhesive material, but its cost is high, and there is a taste, and then the development of PIB, VLDPE as self-adhesive materials, the substrate is now mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE).

Stretch film is also called stretch film, and generally speaking, the two names refer to the same thing. If the concept of stretch film is more extensive, some stretch film can be stretched, some stretch film cannot be stretched, or the elongation rate is low, so stretch film belongs to the category of stretch film.

Stretch film is also stretch film, but the name is different. Strictly speaking, the concept of stretch film is broader, some stretch film can be stretched, some stretch film can not be stretched, or the elongation rate is low, so stretch film belongs to the category of stretch film.

PE stretch film features: better transparency, harder. The color is pure transparent. PVC stretch film features: good softness, the color is mainly light blue.

In fact, the use of stretch film is to make good use of the winding force and retraction of the film, bundle the product into a compact, fixed unit, so that the scattered small pieces become a whole. This form is very powerful for the product to not appear any looseness and separation in many environments, and at the same time, the packaged product will not show some sharp edges and stickiness, causing unnecessary damage. Not only that, the stretch film can also make a protective surface formed around the product, although this protection is only the primary, but it can well achieve the purpose of dustproof, moisture-proof, waterproof and anti-theft, and it can be used to package items in a more effective way due to the adverse consequences caused by uneven force.

Question: What about plastic film?

Answer: The stretch film plays an important role in the transportation of the product is also obvious, because the stretch film has the force of stretching and retracting, so the pallets of the product can be tightly wrapped together, so as to prevent the mutual dislocation and movement of the products during the transportation process, and accidents. Plastic film is just a simple material, which is inferior to stretch film in many ways, so that the object of its application is also different.

Stretch film is stretch film, which is used for packaging.
