Problems solved by technology

Its disadvantages: the foamed PE layer and the polyvinylidene chloride in the composite gasket are separate layers, which are combined with aluminum foil and adhesives. Not only is the process complicated, the manufacturing cost is high, and the produced The thickness of the gasket is thick, and the heat conduction efficiency is low during electromagnetic heating, resulting in high electromagnetic induction heating power, high energy consumption, pollution to the environment, and a direct impact on the health of the operator

Embodiment 1

[0010] Example 1: Refer to the attached figure 1 . A functional bottle mouth sealing gasket intermediate body. The foam layer 1 in the bottle mouth sealing gasket and the heat sealing layer 2 in the bottle mouth sealing gasket are thermally bonded. The foam layer 1 is a polyethylene foam layer. The heat-sealing layer 2 is a polyolefin layer.

Embodiment 2

[0011] Example 2: Refer to the attached figure 2 . On the basis of Example 1, the two sides of the aluminum foil 4 are respectively compounded with the surface layer (polyester layer) 3 of the bottle closure gasket and the functional bottle closure gasket intermediates (1, 2).

Embodiment 3

[0012] Example 3: On the basis of Example 1 or 2, a method for manufacturing a functional bottle-top sealing gasket intermediate, firstly foaming polyethylene, and then melting the foamed polyethylene melt and polyolefin The body is respectively placed in the polyethylene cavity and polyolefin cavity in the composite mold, and then the polyethylene and polyolefin are extruded through the composite die forming head to obtain a polyethylene foam surface and a polyolefin surface. Intermediate of functional bottle sealing gasket.

Abstract

The invention relates to a functional bottle sealing gasket middle body and a manufacturing method of the functional bottle sealing gasket middle body. The functional bottle sealing gasket middle body has the function of a foaming layer in a bottle sealing gasket and the function of a hot sealing layer in the bottle sealing gasket, and the foaming layer in the bottle sealing gasket and the hot sealing layer in the bottle sealing gasket are bonded through hot melting. The functional bottle sealing gasket middle body and the manufacturing method of the functional bottle sealing gasket middle body have the advantages that the middle body has both the function of the foaming layer in the bottle sealing gasket and the function of the hot sealing layer in the bottle sealing gasket, the laminated structure of a bottle sealing gasket in the prior art is changed, an aluminum foil layer is combined with polyester directly, a functional layer is thin, electromagnetic induction efficiency is high, power for electromagnetic induction is lowered, the environment is protected, and physical health of operators is facilitated.

Description

Technical field [0001] The invention relates to a functional bottle mouth sealing gasket intermediate which not only has the function of a foaming layer in the bottle mouth sealing gasket, but also has the function of a heat sealing layer in the bottle mouth sealing gasket and a manufacturing method thereof, belonging to the bottle mouth sealing gasket Intermediate integrated layer manufacturing field. Background technique [0002] CN1970289A, the name "high-sealing foamed PE composite gasket", is made of foamed PE, art paper, aluminum foil, and polyvinylidene chloride, which are four layers of materials bonded together in sequence. The main component of the gasket is foamed PE material, which has a high degree of elasticity, which can meet the size of various bottle mouths and ensure the sealing effect. Its shortcomings: the foamed PE layer and polyvinylidene chloride in the composite gasket are separate layers, and they are compounded together by aluminum foil and adhesives. N...
