There are many properties to be controlled in the manufacture of flexible packaging regardless of the substrate used (aluminium, LDPE, nylon, paper, etc.).
Properties such as chemical resistance, thermoplasticity, flexibility, barrier properties, low heat sealing temperature, etc., are considered when designing coatings in flexible packaging.
Gresalla Química formulates and manufactures dispersions of copolymers that provide all the properties required for the good behaviour of the packaging.
They are dispersions in an aqueous medium, designed to be applied with a coating unit for “first” application.
