Related applications of stretch wound film
Stretch packaging film generally includes mechanical packaging and manual packaging, and is mostly used in food industry, chemical industry and so on. Stretched film packaging does not need heating, saves energy, has high tensile strength, sufficient viscosity, high transparency and convenient use, so it has gradually developed into the mainstream of packaging in the world.
What are the classifications of stretched films?
There are also many kinds of stretched films. For example, hand-drawn films can be classified into many types according to their thickness, thinness, width and color, while machine-drawn films can be classified according to their thickness, width and elongation. At present, there are more than 150 factories producing stretched films in China alone, with a huge output. The main raw materials are high viscosity polymers, such as polyvinyl chloride and low density polyethylene. At present, the main production processes are generally divided into two types, one is casting process and the other is blow molding process. The advantages and disadvantages of the two processes are different, and the raw materials used are also different. Different processes are also selected according to the needs of different stretched films.
Related prices of stretched and wound films
The prices of stretched films on the market are also different. Stretched film has different prices in the market according to different uses, and different thickness and width will affect the price. For example,
PE transparent stretch wound film, 19um thin, 50cm long, 40 yuan price;
9 1.4 mesh high viscosity PE stretched film, specification 2.8KG/ roll, price 42 yuan;
Waterproof stretch film for industrial machinery, thickness 0.02mm, volume 5 kg, price 58 yuan;
Some dustproof and waterproof stretch films used for pallet packaging, the thickness is 0.02mm-0.025mm, 2.8kg/ roll, and the price is 37 yuan;
How to calculate the price of stretched film?
1. If you sell by quantity, you will be suspected of short weight.
2. If you sell by kilogram, it is the most commonly used method and the most intuitive. It's clear when measured with an electronic scale. Of course, the thickness must be specified. Same weight? The length of 17 micron is 30% different from that of 25 micron. It used to be 3000 Jin a month, but now it is enough to use 2 100 Jin.
3. It is most cost-effective to trade by the meter, because when winding and packing, the number of meters is the most needed. Let me give you some examples: Take a roll with a net weight of 2.3kg as an example. 18? Micron thick, 450 mm wide and 300 m long. Take a roll 12KG as an example, the machine film thickness is 23 microns, the thickness is 500mm, and the length is 1 100 m.
Stretch wrapping film packaging can effectively protect goods, prevent rain, water and moisture, improve the added value of goods and reduce the packaging cost by more than 50%. Here is a calculation method for you! Winding film weight = length * thickness * density? . Namely: thickness (mm)* length (m)0.92= weight (KG). Usually we can calculate according to the above formula, which will be more convenient and will not be easily fooled. ? The specific calculation method, you can also refer to the stretch film how much is a kilogram to explain.
Introduction of stretch wound film manufacturers
Haimen Huatai plastic co., ltd
Haimen Huatai Plastic Co., Ltd. is located in Haimen Economic Development Zone, Jiangsu Province. The company is located in the first bridgehead of Shanghai Unicom in the north wing of the Yangtze River Delta. An important hub connecting the north and the south. It can cover more than 20 modern cities such as Shanghai, Suzhou and Wuxi within 200 kilometers, and the land and water transportation is very convenient.
The company covers an area of about 20,000 square meters, has advanced production equipment and good environmental protection facilities, and has been specializing in the production of industrial winding films for nearly 65,438+00 years. Now the annual output has exceeded 1 10,000 tons. The product has the characteristics of high tensile strength, puncture resistance, transparency, self-adhesion, etc., which can reduce the packaging cost, play the role of dust-proof, moisture-proof and cleaning, and improve the overall packaging strength. Over the years, the company has won high praise from users for its quality and service!
Advantages:
1. Stretch packaging saves raw materials than shrink packaging, and there is no need for heat shrink packaging machine, which saves energy.
2. High strength, large elastic pulling force, which can tightly wrap the goods with any geometric shape, and can avoid the damage caused by binding, and has good anti-loosening, rain-proof, dust-proof and anti-theft effects.
3. High-performance resin and auxiliary materials can be used to meet the needs of different users to the greatest extent.
4. It can manufacture single-sided sticky products, reduce the noise during winding and stretching, and reduce dust and sand grains during transportation and storage.
Features:
It has high transparency and good luster.
Shrinkage is rapid at low temperature.
At high speed, the sealing performance is good.
Low temperature and high shrinkage, suitable for small packaging? Used in food field (special type of food)
One-step system and semi-automatic L-shaped shrink sealing roller are ideal choices.
A drum with a diameter of 20CM is also suitable for small machines.
Effective width: 200 ~ 800 mm
Effective thickness:18,20,30,40μ m.
Main advantages of stretched film:
Thin thickness and good cost performance.
Transparent appearance, double-sided tape
Non-toxic, tasteless and safe.
Convenient use and high efficiency.
High buffer strength
Good retraction rate
Puncture resistance
The plastic wrap with good tear resistance can be divided into PE plastic wrap, stretch plastic wrap and PE plastic wrap. Stretch wound film, PE slit wound film
PE winding film is an industrial film packaging product with high tensile strength, high elongation, good self-adhesion and high transparency. It can be used for manual film winding and machine film winding, and can be widely used for centralized packaging of various goods. PE cling film is mainly made of several different brands of polyurethane resin, which has puncture resistance, super strength and high performance. It wraps the goods stacked on the pallet, making the packaging more stable and tidy and super waterproof. Widely used in foreign trade export, paper making, hardware, plastics and chemicals, building materials, food, medicine and other industries.
PE slit laminating: It is made of high-quality LLDPE as the base material, adding high-quality tackifier, heating, extruding, casting and cooling by a cooling roller. It has the advantages of strong toughness, high elasticity, tear resistance, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided bonding and double-sided bonding, and can save materials and labor when used.
Stretch winding film has a wide range of applications. Because of its good viscosity and ductility, it is now used in most factory packaging. ? The appearance of stretched plastic wrap facilitates the packaging of our food industry, chemical production industry and other products, and provides more convenient help for the packaging of our import and export goods, which can make food waterproof and fresh, and avoid the collision of important goods in the import and export process. It is the most successful invention in the packaging industry since the 20th century, and we should make good use of it in the future. Let's introduce the price of stretched film to you.
