Profit analysis of polyethylene cold wrapping Enterprises
The profit problem of polyethylene cold wrapping enterprises is a question that many people are curious about, but the specific profit depends on the market situation. Heat shrinkable band
Polyethylene cold tape, also called polyethylene anticorrosive cold tape, is a kind of film packaging material with PE as the main raw material. It can be used for manual film pulling or automatic winding machine. The following are the four advantages of Dongying Lantian Plastic Co., Ltd., which are summarized according to the customer's usage.
1, save packaging costs: the use of polyethylene cold wrapping products for packaging, can effectively reduce the cost of use, polyethylene cold wrap around only about 15% of the original box packaging, heat shrinkable film about 35%, about 50% of the carton packaging. At the same time, it can reduce workers' labor intensity, improve packaging efficiency and packaging grade.
2, good stability: Polyethylene cold wrap with super strong tightness and shrinkage, can be tightly and fixedly strapped into a unit, so that scattered parts become a whole, even in adverse circumstances, there is no loose and separation products, and no sharp edges and sticky, so as not to cause damage.
3, the packaging is beautiful: with the shrink force of polyethylene after the cold wrapping, the product is wrapped and wrapped, forming a compact, space free unit, so that all the pallets are tightly wrapped together, so that hard products can be tightly attached to the soft products, especially in the paper industry and textile industry.
4, good protection performance: Polyethylene cold wrap around the product form a very light, protective appearance, so as to achieve dust-proof, oil proof, moisture-proof, waterproof, anti-theft purposes. It is important that polyethylene wrapped in cold wrapping to make the packaging products evenly stressed and avoid damage caused by uneven forces. This is unmatched by traditional packaging methods such as strapping, packing belt and polyethylene cold wrapping.
First, take advantage of regional advantages, integrate excellent domestic logistics packaging enterprises, and cultivate regional packaging platform:
1. marketing promotion channel platform;
2. product display platform;
3. warehousing and logistics platform;
4. after-sales service platform;
Two: production R & D platform to build
1. material production research and development;
2. build automatic and intelligent equipment to form the protection of independent intellectual property rights;
3. use platform and location or industry advantages to integrate domestic excess capacity and foreign advanced technology and ideas;
The drawing film must be stretched and the mechanical form of the pallet is directly stretched and pre stretched. Pre stretching is divided into two kinds, one is roller pre stretching, the other is electric stretching. Direct tension is done between the pallet and the membrane. This method has low drawing ratio (about 15% ~ 20%). If the tensile ratio exceeds 55% ~ 60%, the film will be reduced and the puncture performance will be lost. And at 60% elongation, the pulling force is still very large. For light goods, it is likely to deform the goods.
Good viscosity makes the packaging film and layer sticking together to make the goods solid. The method of obtaining sticky mainly includes two kinds: one is to add PIB or its masterbatch to the polymer, and the other is to mix VLDPE. PIB is a semitransparent viscous liquid. Direct addition requires special equipment or equipment modification. PIB masterbatch is commonly used. The migration process of PIB usually takes three days. In addition, it is also affected by temperature. When the temperature is high, the viscosity is strong. When the temperature is low, it is not sticky, and the viscosity decreases greatly after stretching. As a result, the finished film is stored in a certain temperature range (the recommended storage temperature is between 15 and 25 degrees C). Blending VLDPE is slightly sticky, but has no special requirements for equipment. The viscosity is relatively stable. It is not controlled by time. But it is also affected by temperature. When the temperature is higher than 30 degrees, it is relatively sticky. When the temperature is less than 15 degrees, the viscosity is slightly worse. It can adjust the viscosity LLDPE to achieve the desired viscosity. This method is adopted in three layer co extrusion. Anticorrosive tape
