Abstract

The invention discloses a composite packaging material used for healthy tea sealed package. The composite packaging material solves the technical problem that in the prior art, a composite packaging material is poor in pulling strength and heat seal strength through attaching of a heat seal layer, a first graphene layer, an aluminum foil layer, a second graphene layer, a first bonding layer, a brown paper layer, a second bonding layer, a thin film layer and a printing layer. A first motor output shaft drives a discharging screw to rotate, the discharging screw mixes a pre-mixture and extrudesthe pre-mixture out of the bottom of a discharging cylinder, the extruded pre-mixture enters an inner cavity of a coating box, a third air cylinder piston rod shrinks to drive a hydraulic rod to descend, the hydraulic rod drives the discharging cylinder to descend through a cylinder sleeve, the discharging cylinder drives a down pressing plate to descend, the down pressing plate extrudes the pre-mixture in the coating box downwards to the surface of a coating roller, a third motor output shaft drives a supporting roller to rotate, the supporting roller drives a first transmission roller and asecond transmission roller to rotate through a coating belt, and in the rotating process of the coating roller, a uniform spreading belt uniformly spreads the pre-mixture on the surface of the coatingroller.

Description

technical field

[0001] The invention relates to the technical field of composite packaging materials, in particular to a composite packaging material used for hermetic packaging of health-preserving tea. Background technique

[0002] On the basis of the development of the packaging industry, the packaging of articles has also been developed accordingly. From simple paper packaging, to single-layer plastic film packaging, to the widespread use of composite materials. Composite packaging materials can make the contents of the packaging have the characteristics of moisturizing, fragrance preservation, appearance, freshness, light protection, penetration prevention, and extended shelf life, so they have developed rapidly.

[0003] The patent document (CN201510988101.9) discloses a preparation method of a multi-layer composite polymer packaging material, which uses the oil resistance, corrosion resistance and blocking properties of the modified PET layer to further strengthen th...
