Technical Field

[0001] The utility model relates to the technical field of packaging, and belongs to a polypropylene resin packaging structure. Background Art

[0002] Polypropylene resin is a common plastic material with good heat resistance, chemical stability and plasticity. In the field of packaging, polypropylene resin is widely used due to its characteristics. Existing polypropylene resins are divided into homopolymer polypropylene and copolymer polypropylene. Homopolymer polypropylene is mainly used for injection molding and extrusion processing, such as food packaging containers, household appliances, etc. Copolymer polypropylene includes block copolymers and random copolymers, which are usually used in occasions that require low-temperature toughness and transparency, such as packaging films, medical supplies, etc.

[0003] The packaging structure made of polypropylene resin has the following characteristics: 1. High transparency and gloss: making the packaged product more attractive. 2. Good barrier properties: having a good barrier effect on moisture, grease, etc. 3. High and low temperature resistance: can maintain good performance in a wide temperature range. 4. Recyclable: good environmental performance, conducive to sustainable development, therefore, polypropylene resin packaging structure is widely used.

[0004] For example, the packaging structure with the prior art announcement number CN218343981U can facilitate the user to pull the tear edge to pull up the tear strip, and can also facilitate the user to tear the first side baffle or the second side baffle along the dotted knife line, thereby simplifying the user's unpacking of the packaging structure and improving the unpacking efficiency of the packaging structure.

[0005] However, the above-mentioned prior art still has the following problems when used: after the existing packaging structure is packaged, it usually needs to be sealed with tape. The viscosity of the tape is easily reduced by environmental factors, which in turn affects the firmness of the packaging structure and reduces the protective effect of the object. Based on this, the utility model provides a polypropylene resin packaging structure with high firmness. Utility Model Content
