Application Of Stretch Wound Film

Application Of Stretch Wound Film Stretch winding film is a packaging method, which uses mechanical stretching device or hand to stretch the film strongly at room temperature to tightly wrap the articles for transportation and storage. This is a very popular packaging method in the world. It adopts imported resin and advanced underflow stretch winding  film extrusion production technology. It has good tensile property, permeability, tear resistance, good self-adhesive, high shrinkage, strong permeability, tight packaging, high transparency and no looseness. Stretch winding film can be widely used in food, fertilizer, mechanical and electrical products, chemical raw materials, light textile products and so on. Single piece or pallet packaging, including other bundled packaging. Stretch winding film application area The packaging of the stretch wound film must be stretched. The stretching forms of pallet mechanical packaging include direct stretching and pre stretching. There are al

Deruna What Is The Use Format Of The Winding Film

What Is The Use Format Of The Winding Film?

1. Sealing

XryGbWMqR0ay8XmtOhVTJA.jpg

The winding film is similar to the shrink film. The film surrounds the whole, and then two hot handles seal the films at both ends together. This is the older use of film winding, which has developed more.

2. Full width

The winding film should be wide enough to cover the film. Some are regular in shape and some are used. The film thickness is 17 ~ 35 M.

3. Manual

The winding film is a relatively simple one in the whole film. The film can be clamped on a frame, held in the hand, on the top, or rotated. It is mainly used for reconditioning after damage. This speed is slow, and the suitable film thickness is 15 ~ 20 m.

4. Stretching film winding machine

This is a common and widely used machine for winding film. The film is fixed on the base and can move up and down. This capacity is very large, about 15 ~ 18 discs per hour. The suitable film thickness is about 15 ~ 25 M.

5. Horizontal machine

Different from others, the film revolves around things and is suitable for carpets, plates, fiberboards, special-shaped materials and other long goods.

6. Paper cylinder

This is one of the newer uses of winding the whole film, which is better than the reducing film used in the old carton. The suitable film thickness is 30 ~ 120 M.

7. Props

The winding film can not only reduce the material consumption but also reduce the storage space. In foreign countries, it was introduced in 1984 for the first time. In a short year, many of them appeared in the market, which has great potential. Suitable film thickness: 15 ~ 30 m;

8. Pipes and cables

This is an example of a special field where equipment is wound at the end of a production line. The fully automatic stretching film can not only replace the tape binding material, but also play a protective role. The applicable thickness is 15 ~ 30 m.

9. Stretching form of mechanism

The winding film shall be stretched. The mechanical stretching includes direct stretching and pre stretching. There are two types of pretension. One is the drum pretension and the other is the electric tension.

The direct stretching of the winding film is to complete the stretching between and the film. This method has a low elongation rate (about 15% – 20%). When the elongation rate exceeds 55% – 60%, the film width will be reduced beyond the original yield point of the film, the puncture performance will be lost, and the film will be easily broken. In addition, with 60% elasticity and large traction, the goods are likely to be deformed for light goods.

Pre tensioning is done by two rollers. The two drums stretched in advance by the drum are connected together in gear. The stretching rate may vary with the gear ratio, and the tension is generated by the rotary table. Stretching occurs in a short distance, and the friction between the drum and the film is large, so the film width will not be reduced, and the original puncture performance of the film will remain unchanged. No stretching occurs during actual winding, which reduces the damage caused by sharp edges or angles, and the stretching ratio can be increased to 110%. The tension mechanism of the electric pretension is the same as that of the roller. However, it is different that the two rollers are driven by electricity. Stretching has nothing to do with. Therefore, it is applicable to light, heavy and irregular goods with strong adaptability. Due to the low hourly tension, the pre stretching rate of this method reaches 300%, which greatly saves materials and costs. Suitable film thickness is 15 ~ 24 M.

coloring process of stretch wrap film

What is the coloring process of stretch wrap film?

What is the coloring process of stretch wrap film? Normal stretch wrap film is a packaging method formed by winding the film at room temperature through a mechanical stretching device or by manual stretching. Stretch wrap film from stretch wrap film manufacturers is tightly packed for products and easy to transport and store. Stretch wrap film is usually produced with imported resin and advanced flow diffraction film extrusion process, followed by the coloring process of stretch wrap film. Coloring Process of Stretch Wrap Film The coloring process of stretch wrap film is a very important one in the production process of stretch wrap film. Next, learn about the coloring process of stretch wrap film according to the requirements of stretch wrap film manufacturers. One of The Coloring Processes for Stretch Wrap Film is Instrument Color Matching This is a method of color matching rolled film using an instrument. It uses measuring instruments such as photometers to replace the functions of

tensile film

What are the tensile film additives?

What are the tensile film additives? The tensile films are widely used because of their light weight, thinness, cheapness, portability, and ease of deformation. In particular, the use and quality of stretch film has increased in the packaging of food and daily necessities, agricultural re-capping materials, etc. The functional requirements for new stretch film materials have also increased. What is Tensile Film? Tensile film, also known as winding film, is an industrial packaging product with the advantages of strong stretching force, strong stretching, good shrinkage, good self-adhesiveness, thin fabric, softness and high transparency. It is used for hand stretch film winding film, also can be used for mechanical winding film, widely used in the packaging of various goods. Bi-directional Tensile Film Auxiliaries Bi-directional tensile film materials are in an important position in stretch film packaging, with bi-directional oriented polypropylene (BOPP), polyester (BOPET), nylon (BOPA

The difference between wrap-around film and stretch film

The difference between wrap-around film and stretch film

The difference between wrap-around film and stretch film Both wrap-around film and stretch film are used to wrap all kinds of products for sale and transportation, playing a protective and firm covering role. The two names refer to the same thing, the concept of wrap film is broader, wrap film is also called stretch film, some wrap film can be stretched, and some wrap film cannot be stretched, or the stretch rate is low, so stretch film is in the category of wrap film, let’s learn the difference between wrap-around film and stretch film together below! Different advantages of wrap-around film and stretch film Wrapping film has high tensile strength, tear strength and good self-adhesive, so it can wrap objects into one and not scatter them during transportation. The film has excellent transparency, wraps objects beautifully, and has the characteristics of objects being waterproof, dustproof, and preventing breakage.  It is mainly blown, and has developed from single-laye
