Acrylic acid coating film and its manufacturing method

Abstract

An acrylic acid coated film is composed of a substrate layer, a coated acrylic paint layer and a sandwich layer between the first two layers. Its preparing process includes such steps as preparing acrylic paint from acrylic emulsion, softened water, smoothing agent and detackifier, coating it on the substrate and baking.

Description

technical field

[0001] The invention relates to a coating film, which belongs to the field of new environment-friendly polymer materials, and is especially suitable for low-temperature heat-sealing, and improves the adhesion of printing ink, and is suitable for high-transparency packaging films printed with water-based inks, and can be applied to low-temperature heat-sealing High-speed automatic packaging (such as biscuits, cakes and other foods), as well as decorative packaging of cosmetics. Background technique

[0002] At present, the packaging of small items (such as small snacks) on the market is often dominated by composite materials. This type of material is widely used, but it is obviously unreasonable, mainly reflected in:

[0003] (1) The thickness of the composite layer of the composite material used in lightweight packaging is too large, resulting in material waste;

[0004] (2) The composite process consumes high energy, and discharges organic solvents that pol...
