Abstract
The utility model discloses a packaging composite film which comprises a base layer, a kraft paper layer, a high barrier layer, an aluminum film layer, an ink layer and a PE layer which are sequentially arranged from inside to outside, wherein the adjacent layers are in composite connection through an adhesive layer. According to the utility model, the high barrier layer adopts the LDEP layer or the EVOH layer, so that the barrier effect is good, and a good barrier effect can be achieved; the tearing resistance and puncture resistance of the composite film can be further improved (only relatively speaking, not the tearing and puncture resistance) by the arranged kraft layer; the PE layer is added with 3-4% of carbon black pigment and ultraviolet light resistant stabilizer, which has the function of shading light on one hand and enhancing ultraviolet light resistant function on the other hand.
Description
Technical Field
The utility model relates to the technical field related to packaging composite films, in particular to a packaging composite film.
Background
Composite films for pharmaceutical packaging requirements for barrier properties high barrier packaging materials for food composite films generally refer to high oxygen barrier materials such as PP, EVOH, etc., but most of the articles for pharmaceutical packaging are sensitive to water vapor and insensitive to oxygen and thus the barrier properties of pharmaceutical packaging are generally dominated by moisture protection. The medicine is a special commodity with high added value, safety and reliability requirements, except the package of Chinese medicinal decoction pieces and low-grade medicinal granules, the medicine packaging composite film is mainly composed of pure aluminum foil composite materials, and the food package is mainly composed of transparent or aluminized packages.
The medical packaging composite film disclosed by the prior publication No. CN209365547U has good physical and mechanical properties, high composite strength, good sealing property, good barrier property, high tearing strength and acid resistance and disinfection resistance; however, the storage of the medicine needs higher water-blocking and isolation performance, and better puncture resistance performance, and in order to solve the problems, the utility model provides a packaging composite film.
Disclosure of Invention
The utility model aims to provide a packaging composite film which solves the problems in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: a packaging composite film comprises a base layer, a kraft layer, a high barrier layer, an aluminum film layer, an ink layer and a PE layer which are sequentially arranged from inside to outside, wherein adjacent layers are in composite connection through an adhesive layer.
Preferably, the base layer adopts one of BOPP layer, BOPET layer, BOPA layer, MT layer and KPET layer.
Preferably, the high barrier layer is an LDEP layer or an EVOH layer.
Preferably, the adhesive layer is one of an outer polyurethane adhesive layer, an acrylic adhesive layer, a methacrylic adhesive layer and an acrylic adhesive layer.
Preferably, the PE layer is added with 3-4% of carbon black pigment.
Preferably, the PE layer is added with an ultraviolet light resistant stabilizer.
Compared with the prior art, the utility model has the beneficial effects that: the high barrier layer adopts an LDEP layer or an EVOH layer, has good barrier effect and can play a good barrier role; the tearing resistance and puncture resistance of the composite film can be further improved (only relatively speaking, not the tearing and puncture resistance) by the arranged kraft layer; the PE layer is added with 3-4% of carbon black pigment and ultraviolet light resistant stabilizer, which has the function of shading light on one hand and enhancing ultraviolet light resistant function on the other hand.
