Abstract

The invention discloses a high temperature resistant blister box capable of being disinfected by steam and a production method thereof. The high temperature resistant blister box capable of being disinfected by steam comprises a box body and a box cover; the box body and the box cover contain the following materials in parts by weight: 85-95 parts of polypropylene, 14-18 parts of polyacrylamide, 5-8 parts of maleic anhydride grafted polypropylene, 16-19 parts of ethylene-propylene copolymer, 12-17 parts of nano silicon dioxide, 2.5-3.5 parts of antioxidant, and 2-4.5 parts of polyethylene wax.The high temperature resistant blister box capable of being disinfected by steam is high temperature resistant, can be disinfected by steam, is unlikely to deform; is high in strength and long in service life; is low in shrinking percentage and unlikely to have hemming deformation; and is sanitary and non-toxic, and can meet the food packaging requirement.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to a steam-sterilizable high-temperature-resistant blister box and a production method thereof. Background technique [0002] Blister box is a plastic product produced by blister technology. It is widely used in daily life and production. It has the advantages of light weight, convenient transportation and good sealing performance. [0003] However, the traditional blister box is made of plastic sheet through vacuum suction, which is not resistant to high temperature, easy to deform during steam sterilization, low tensile strength and impact strength, easy to damage during use; high shrinkage rate, easy to curl and deform ; Can not meet food hygiene requirements, high content of harmful substances. [0004] Based on the above situation, the present invention proposes a steam sterilizable high temperature resistant blister box and its production method, which can effectively solve...
