Преимущества стерильных упаковочных пакетов из бумаги и пластика

With the world's environmental-protection requirements,

sterilized paper-plastic packaging bags

are slowly getting on the right track, so where do the advantages of sterilized paper-plastic packaging bags lie

? Sterilized paper-plastic packaging bags are a new type of packaging bag that is high-strength, anti-aging, high-temperature resistant, moisture-proof, breathable, non-toxic and harmless. They are widely used in packaging food, fresh frozen food, starch, casein, feed, building materials, chemicals, mineral products and other industries.

They have the following six major advantages

PVA has excellent fluidity and film-forming properties, and during pressure lamination it forms a thin film on the inner layer of the sterilized paper-plastic packaging bag, playing a role in composite bonding and moisture protection. Its other surface has many invisible small holes, which can effectively prevent water molecules outside the sterilized paper-plastic packaging bag from entering the bag.

The strength of the sterilized paper-plastic packaging bag is mainly controlled by warp and weft. Because the vinylon water-soluble yarn has the characteristic that the single yarn's

breaking force at 180° remains unchanged. The ignition point of paper is 183 degrees, so the composite bag also has the characteristic of high-temperature resistance.

Because paper is a plant substance that does not easily age, it is opaque. The paper inside and outside the sterilized paper-plastic packaging bag can effectively protect the paper from aging under ultraviolet irradiation, so that the packaging bag together has anti-aging characteristics.

The strength of the sterilized paper-plastic packaging bag is mainly controlled by the warp and weft directions. As the weft disc rotates counterclockwise, many triangular mesh structures form on the outer surface of the inner paper, greatly increasing the internal stress of the packaging bag and giving the packaging bag relatively high strength.

Because during the pressure-lamination process, many triangular mesh structures form on the outer surface of the sterilized paper-plastic packaging bag, increasing the friction coefficient of the bag's outer surface, so that the bags do not slip during stacking

(the height can reach 40 degrees). Plastic Industry Box — an integrated platform for the "internet plus plastics" ecological chain of the food plastic packaging industry.

Six, protecting the environment

Because the vinylon water-soluble yarn has not been treated with resin acetalization, it is soluble in

80℃ hot water to form a glue solution. After soaking, the inner and outer layers of the paper can be recycled to make recycled paper without polluting the environment.

Sterilized paper-plastic packaging bags are also called three-in-one composite paper bags; they are a small bulk container, mainly transported by manpower or forklift. They are convenient for transporting small amounts of bulk powder and granular materials. They have the characteristics of high strength, good waterproof performance, high aesthetics and convenient loading and unloading, and are a popular and practical packaging material.
