Abstract

The invention relates to a yogurt eight-connected cup made of a PP material, a modified PP sheet for manufacturing the yogurt eight-connected cup and a preparation method of the modified PP sheet. PP is adopted to replace PS to serve as a main material of the yogurt eight-connected cup. The cost of packaging materials is greatly reduced, and the cost is saved by 16%-30% on the whole; more recycling paths (including turnover boxes, injection molding parts and the like) are provided, the cyclic utilization rate of materials is increased, and greater environment friendliness is achieved; and the film covering cost is reduced. In addition, from the aspect of the use effect, the PP yogurt eight-connected cup is not obviously different from a PS yogurt eight-connected cup on the market.

Description

technical field [0001] The present invention relates to a yogurt eight-connected cup, a PP sheet for manufacturing a yogurt eight-connected cup and a preparation method thereof, in particular to a PP-made yogurt eight-connected cup, a modified PP sheet for manufacturing a yogurt eight-connected cup and its preparation method. Background technique [0002] At present, the commonly used yogurt cup forms on the market are mainly divided into two forms: single cup and continuous cup. The materials used in single-cup yogurt cups mainly include: paper plastic, glass, polypropylene PP, polystyrene PS, etc.; while the materials used in continuous-cup yogurt cups are mainly polystyrene PS. [0003] The preparation process of yogurt cups varies according to the form of yogurt cups. For example, the preparation process of a single-cup paper-plastic yogurt cup: heat-sealing the body of the coated paper cup, fitting it with the bottom paper, crimping the cup mouth, and sealing it with ...
