Lamination technology and conditions: (applied to most dry lamination equipment)
(1) Environmental conditions: the work site shall be dry and clean, and the relative humidity of the air shall not exceed 80%.
(2) Coating method: gravure coating.
(3) Coating amount (dry-based): the adhesive solution will be applied on the smooth and non-absorbent substrate surface, while the dry adhesive amount shall be selected within the range of 2.5-3.5 g/m2. For the BOPP/CPP and BOPP/PE structures, the lamination adhesive application amount shall be mainly 2.5g/m2. For the polyester, nylon, aluminum foil, aluminum laminated films and other structures, the adhesive application amount shall be 3-4 g/m2 in general. For the boiling substrate, the adhesive application amount (dry-based) shall be 4.0-6.0 g/m2 in general.
