Problems solved by technology

However, the tensile properties of the tropical-type blister aluminum produced by most manufacturers are not good. The tropical-type blister aluminum produced by some manufacturers still has disadvantages such as poor heat sealing, insufficient sealing, easy delamination of the aluminum layer, uneven surface gloss, and monotonous color.

Embodiment 1

[0014] Use the nylon layer as the base layer, coat a layer of polyurethane, then bond the soft aluminum foil layer, and then coat the heat-sealing coating on the bonded soft aluminum foil layer. The thickness of the nylon layer is 15 microns, and the soft aluminum foil layer is The thickness is 75 microns.

Embodiment 2

[0016] The nylon layer is the base layer, coated with a layer of polyurethane, and then bonded with a soft aluminum foil layer, and then coated with a heat-sealing coating on the bonded soft aluminum foil layer. The thickness of the nylon layer is 25 microns, and the thickness of the soft aluminum The thickness is 60 microns.

Embodiment 3

[0018] Nylon layer 1 is the base layer, coated with a polyurethane layer, then bonded with a soft aluminum foil layer, and then coated with a heat-seal coating on the bonded soft aluminum foil layer, the thickness of the nylon layer is 30 microns, and the soft aluminum foil layer is The thickness is 45 microns.

Abstract

The invention relates to a high seal and tropical-typed bubbling hood aluminum, comprising a nylon layer (1) which is taken as a basic layer; the bubbling hood aluminum also comprises a polyurethane binder (2), a soft aluminum foil (3) and a heat-seal coating (4) which cover the nylon layer (1) in sequence; the bubbling hood aluminum has the beneficial effects that the depth stretching performance is excellent, bubbling hoods with different shapes and depth being deeper the that of a biggest No. 00 capsule can be formed by mould pressing without damage, the compound strength between the aluminum layer and the nylon is high, thus no delamination occurs when in forming; in addition, when heat-sealing is carried out on the bubbling hood aluminum and PVC, an exiguous heat-sealing channel can not be produced; good tightness can be maintained after heat-sealing package, thus the moisture and the light are protected and the quality guarantee period of medicines can be prolonged effectively. Meanwhile, special color paste is added into the binder, which causes a more colorful appearance.

Description

technical field [0001] The invention relates to a packaging material, in particular to a plate-shaped packaging material with high sealing and high pellet density for medicines and health care products. Background technique [0002] At present, with the improvement of people's living standards, the quality requirements for medicines that are related to people's life safety are getting higher and higher, so the requirements for packaging materials that play a protective role in medicines or health care products are also getting higher and higher. Because some good and expensive medicines or health care products generally have the characteristics of being easy to deteriorate when exposed to moisture and easy to decompose when exposed to light, the packaging materials of these products are not only required to have a good barrier to oxygen and moisture, but also to be able to avoid light. , and have good machinability and eye-catching colors. [0003] Traditional packaging for...
