Description

Technical Field

[0001] The utility model relates to the technical field of polypropylene films, in particular to a strong and non-slip polypropylene film. Background Art

[0002] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer. It is one of the lightest varieties of all plastics currently available. It is particularly stable to water, with a water absorption rate of only 0.01% in water. Its molecular weight is about 80,000 to 150,000, and it has good formability. However, due to its large shrinkage rate, thick-walled products are prone to dents, and it is difficult to meet the requirements for some parts with high dimensional accuracy. The product has a good surface gloss, high crystallinity, and regular structure of polypropylene, so it has excellent mechanical properties. The absolute value of the mechanical properties of polypropylene is higher than that of polyethylene, but it is still a relatively low variety among plastic materials. Polypropylene with a larger isotactic index has a higher tensile strength, but with the increase of the isotactic index, the impact strength of the material decreases. It is widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, steamed food packaging, fast food packaging, etc.

[0003] For example, Chinese patent CN210553409U discloses a high-barrier and strong-toughness polypropylene film, comprising a polypropylene film base, the top and bottom of the polypropylene film base are fixedly connected with a barrier layer, the outer side of the barrier layer is fixedly connected with a toughness reinforcement layer, the barrier layer comprises a silicon oxide coating and a PVDC layer, the bottom of the silicon oxide coating is fixedly connected with a PVDC layer, the toughness reinforcement layer comprises a COC molecular layer and a BOPET film layer, and a BOPET film layer is arranged at the bottom of the COC molecular layer. However, the polypropylene film is in direct contact and friction with other objects, and the polypropylene film is easily worn and damaged, thereby reducing the service life of the polypropylene film, being inconvenient for users to use, and reducing the practicality of the polypropylene film. Therefore, a strong, tough and non-slip polypropylene film is proposed to solve the above-mentioned problems. Utility Model Content
