What are the characteristics of stretch film? What are the advantages of stretch film

Stretch film is also called stretch film, the meaning of stretch film is: refers to a packaging material used in packaging and packaging. It has a tensile effect.

A 1 meter membrane can usually be pulled between 3-5 meters. It is usually used more often in the logistics industry. The main thing is environmental protection.

Easy to use. It is not easy to fall off and so on. It is the first in China to produce PVC winding film with PVC as the substrate and DOA as a plasticizer and self-adhesive.

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 it has a taste, and then developed with PIB, VLDPE as self-adhesive materials, and the substrate is now LLDPE as the square, including C4, C6, C8 and metallocene PE (MPE).

Stretch film has a wide range of applications, mainly used in conjunction with pallets to package loose goods as a whole instead of small containers. Because it can reduce the cost of bulk cargo transportation and packaging by more than 30%, it is widely used in the whole package of hardware, minerals, chemicals, medicine, food, machinery and other products; In the field of warehouse storage, foreign countries also use stretch film pallet packaging for three-dimensional storage and transportation to save space and land occupation. Effect of cooling roll temperature.

The temperature of the cooling roller increases, the yield strength increases, but the rest of the performance decreases, so the temperature of the general cooling I roll is controlled at 20 30. The tension of the cast line affects the flatness and tightness of the film, and if PIB or its masterbatch is used as the adhesive layer, it also affects the migration of PIB and reduces the final viscosity of the film. The tension is generally not more than 10kg, and the stress remains in the film roll if it is too large, which reduces the elongation and other properties, and is easy to cause film breakage.

Application form of stretch film.

People who have used the stretch film know that the stretch film has strong puncture resistance and good retraction performance, and the goods packaged by the stretch film can be tightly wrapped in the middle, and it is not easy to disperse without a beat. The winding film can also play a role in waterproof, anti-rotten moisture, dust-proof, etc., and transparent and beautiful, without opening the package, you can clearly see the goods inside, to avoid mistakes when providing.

Question 1: What is the material of the stretch film It is mainly based on PE polyethylene.

Question 2: What is the material of the stretch film? What are the ingredients?

Please give me advice! PE stretch film is made of PIB and VLDPE as self-adhesive materials, and the substrate is now mainly LLDPE (linear low-density polyethylene), including C4, C6, C8 and metallocene PE (MPE).

Question 3: What is the raw material of the stretch film? Rice, mung beans, melon seeds, star anise, rice 2 yuan, mung beans 1 yuan, melon seeds are very expensive, star anise has eight corners. That's it.

Question 4: What is the spiral film used for? Stretch film is also called stretch stretch film, organic stretch film and hand stretch film two categories, Jinqiang stretch film is based on high-quality LLDPE, with high-quality tackifier, heating, extrusion, casting, and then cooled by the chilling roller, with strong toughness, high elasticity, tear resistance, high viscosity, dustproof, waterproof, single-sided sticky and double-sided sticky and other advantages, is glass ceramics, tire rubber, drip irrigation tape, cartons, iron cans, aluminum-plastic profiles, forage and other product packaging supplies.

Hope it helps. Hope!

Question 5: What is the difference between PE stretch film and PVC stretch film? 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.

Question 6: How is the stretch film made The domestic stretch film, also known as PE stretch film, is mostly sticky on one side, and the casting method is generally used (the blow molding method is mostly used to produce PVC toxic winding film), which is heated and melted and then extruded by the extruder to blow into a bubble tube shape in the machine head, and then evenly flattened into the feeder, rolled by the rolling mill, and repeated on three sides. Then the temperature of the control machine is transmitted to the cooling pool, which is cooled and rolled.

Summary. The stretch film produced by Tiandi packaging materials **** is also called elastic film, and it is also called self-adhesive film, stretch film, and tension to wrap the goods tightly to achieve the purpose of protecting the goods.

Features: Good transparency, dustproof, anti-theft, can pack film.

When using, you can use the self-adhesive elasticity of the film itself to stretch and wrap it, relying on the viscoelasticity of the surface of the film and the pull used in use to wrap several products of different shapes together to avoid loss and omission.

Stretch wrapping film can be used for transport packaging, such as wrap wrapping for large pallets, wrap wrapping for containers, boxes, and can also be used for short-distance transportation and sales packaging, such as daily necessities packaging, stainless steel pipes, plastic pipes, etc

1. Stretch the film.

It is produced with imported linear polyethylene LLDPE resin and tackifier special additives. It is the first in China to produce PVC wraparound film with PVC as the base material, DOA as a plasticizer and self-adhesive effect. from a single layer to a second and third floor; At present, the casting method is mainly used to produce LLDPE stretch film, and the early LLDPE stretch film is mostly blown film.

This is because the production of cast lines has the advantages of uniform thickness and high transparency, which can be applied to the requirements of high magnification pre-stretching. Because single-layer casting cannot be single-sided adhesive and the application field is limited, high-quality stretch film should have the characteristics of high transparency, high longitudinal elongation, high yield point, high transverse tear strength and good puncture performance.

2. Stretch film.

Also known as stretch film, heat shrinkable film, the earliest in China with PVC as the base material, DOA as a plasticizer and self-adhesive production of PVC stretch film. However, its cost is high, PE stretch film first uses EVA as a self-adhesive material, and has a taste, and then develops PIBV and LDPE as self-adhesive materials, and the substrate is now mainly LLDPE, including C4, C6, C8 and metal PEMPE.

from a single layer to a second and third floor; At present, the casting method is mainly used to produce LLDPE stretch film, and the early LLDPE stretch film is mostly blown film. This is because the production of cast lines has the advantages of uniform thickness and high transparency, which can be applied to the requirements of high magnification pre-stretching. Since single-layer casting cannot be adhered on one side, the application field is limited.

Single-layer and double-layer casting is not as wide as three-layer casting in the selection of materials, and the formula interest is also high, so it is more ideal to use the structure of three-layer co-extrusion. High-quality stretch film should have the characteristics of high transparency, high longitudinal elongation, high yield point, high transverse tear strength, and good puncture performance.

3. What are the advantages of pre-stretched stretch film over traditional stretch film?

Under the same weight, the actual packaging area of ultra-thin stretch film is about 3 times that of traditional stretch film on the market. Compared with traditional stretch films, the cost savings are considerable. Moreover, our green stretch film is a high-strength pre-stretched single-sided adhesive stretch film, which is quite convenient to use, saving labor and money.

The outer surface of the packaging is not easy to stick to dust, clean and hygienic.
