Abstract

The scheme of the invention relates to thermal-band type bubbling hood aluminum coated at a fixed point and a preparation technology of the thermal-band type bubbling hood aluminum. The thermal-band type bubbling hood aluminum comprises an aluminum foil layer, wherein the aluminum foil layer is provided with a first surface and a second surface which are opposite, the first surface is provided with a polyurethane adhesive layer, and a polyamide layer or a polyester layer is arranged on the surface of the polyurethane adhesive layer; the second surface is provided with VC glue layers which are coated at fixed points; and ink printing blocks are also arranged between the polyurethane adhesive layer and the polyamide layer or the polyester layer. According to the thermal-band type bubbling hood aluminum and the preparation technology thereof disclosed by the scheme of the invention, a fixed-point coating manner is adopted, the coating quantity of VC glue can be reduced to an original value namely 40%, and the glue coating cost is saved by 60% or above; besides, the discharge quantity of VOCs is also reduced by 60%, the energy consumption is reduced, besides, the environmental protection in the production of thermal-band aluminum is also substantially improved, and the effects of saving energy and reducing emission are achieved. The method has the characteristics of being simple, low in implementation cost, good in quality guaranteeing effects and the like.

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging materials, in particular to a fixed-point coating tropical-type blister aluminum and a preparation process thereof. Background technique [0002] Tropical blister aluminum foil is a combination of thermoformed plastic blister and cold-formed composite aluminum. The blister packaging keeps the blister size unchanged, and the area around the blister is slightly wider for the cold-formed tropical blister composite film It can be sealed with thermoforming blisters, which makes up for the problems of poor light transmission and water resistance in traditional aluminum-plastic packaging, and is gradually being accepted by domestic manufacturers. [0003] Tropical blister aluminum (also known as aluminum-plastic aluminum) is composed of polyamide or polyester / aluminum / adhesive, which is a composite of these materials through special equipment at a certain temperature and pressure. Sheet material ...
