Abstract

The invention relates to a preparation method of a sterilization type easy-to-tear sealing cover film. The preparation method is used to prepare a sterilization type easy-to-tear sealing cover film which comprises but is not limited to a printing base layer and a heat sealing layer. The preparation method comprises the following steps of: preparing the printing base layer and carrying out composite molding. The preparation method has the advantages that the printing base layer and the heat sealing layer are bonded together through gravure printing in the first step and dry compounding in the second step, and the printing layer is formed by printing with cooking ink, so that the surface of the whole composite film has good high-temperature-resistant sterilization performance, sterilizationcan be performed at the high temperature of 100-135 DEG C for 30-60 min, it can be guaranteed that a sterilized product does not discolor or have bag breakage or wrinkles, the quality of the product is stable within the quality guarantee period, the preservation time of the product is greatly prolonged, the adopted printing ink, glue and materials all conform to food safety laws and regulations, and great market prospects and social and economic benefits are achieved in the field of sterilization type medical instruments and the field of health care products.

Description

technical field [0001] The invention relates to a preparation method of a sterilized easy-tear lid film. Background technique [0002] With the rapid development of the packaging industry, convenient and easy-to-use packaging products are widely used in all walks of life, and the easy-to-tear lid film is one of them. Easy-to-tear cap film, also known as easy-to-peel cap film, easy-to-peel cap film, is mainly used in food, medicine, cosmetics packaging and other industries in daily production and life.
