Abstract

The invention provides an easy-to-adhere nylon film and a preparation method thereof, and a nylon-based composite film and a preparation method thereof, and belongs to the technical field of packagingmaterials. The easy-to-adhere nylon film comprises a nylon base material layer and an easy-to-adhere layer arranged on at least one surface of the nylon base material layer, wherein the nylon base material layer consists of three layers of co-extrusion biaxially oriented nylon films, namely a first surface layer, a core layer and a second surface layer in sequence from top to bottom; the first surface layer and the second surface layer independently comprise nylon resin, a slipping agent, an anti-blocking agent, an easily-bonded functional material and an antistatic agent; the core layer comprises nylon resin; the easy-to-adhere layer is prepared from the following raw materials through a cross-linking reaction: modified water-based hydroxyl acrylic resin, a nano-silica grafted hyperbranched polymer, an ethylene-maleic anhydride copolymer, a solvent, a cross-linking agent and a slipping agent. The easy-to-adhere nylon film provided by the invention has excellent adhesion and is not easy to adhere.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, and in particular relates to an easy-adhesive nylon film and a preparation method thereof, a nylon-based composite film and a preparation method thereof. Background technique [0002] Biaxially oriented nylon (BOPA) film has the advantages of high strength, good toughness, good transparency, wide temperature range, excellent barrier properties, and good puncture resistance, so it is widely used in food packaging, daily chemical packaging, and pharmaceutical blister packaging. , Electronic product packaging and other technical fields. But in practical application, BOPA film needs to be used in combination with other film materials. Therefore, it is usually necessary to carry out secondary processing on the surface of BOPA film, such as physical treatment such as halo treatment and plasma treatment, or chemical treatment with chemical reagents such as acid and alkali to improve the adh...
