Problems solved by technology

[0003] CN201610578977.0 reported a plastic woven bag made of BOPP as the main material, which solved the hygienic needs of flour moisture-proof, moth-proof, and pollution-proof, but due to the performance of the woven bag itself, its storage time cannot be too long
CN201410011003.5 describes a kind of flour packaging film coated with PE film by modified polypropylene, and then bonded together through the middle layer of polyurethane. This flour packaging film solves the problems of flour antistatic and heat sealing, but it needs to first Preparation of modified polypropylene emulsion, and then compounding and coating, the production process is more complicated, the cost is higher, and it is difficult to promote in industrial use

Abstract

The invention discloses a special polyethylene flour bag packaging film, and belongs to the field of packaging films. Metallocene imported from America is added in the outer layer, metallocene B and Aimported from Japan are added into the middle layer and the inner layer, the formulas of the outer layer, the middle layer and the inner layer are different and are mixed evenly, a three-layer film is formed by a co-extrusion mold head to be extruded, and the special polyethylene flour bag packaging film is obtained. The sealing performance is better, the cost is better, the preparation process is concise, the heat-seal temperature is low, firmness is better, and the special polyethylene flour bag packaging film is very suitable for small-batch packages.

Description

technical field [0001] The invention relates to a polyethylene flour bag packaging special film, which relates to the preparation of a polyethylene flour bag packaging special film by using high-grade imported olefin raw materials and other auxiliary agents as raw materials, and belongs to the field of packaging films. Background technique [0002] With the improvement of people's living standards, people have better requirements for the refinement of life. The previous flour packaging is generally in woven bags, and each bag weighs 15-25kg. Some families need to eat a bag for several months or even a year. year. At the same time, because the flour packed in woven bags is susceptible to moisture, it is not conducive to the storage of flour, and the flour packed in woven bags will inevitably have a large amount of flour dust during transportation and storage, causing certain safety hazards. Therefore, flour packaging with small packaging and longer storage time is a trend. ...
