Abstract

The invention discloses a thermal insulation composite paper container capable of bearing liquid. The following layer structure composition is adopted for making a paper board of the container: a waterproof anti-reflection layer compounded by a plastic film and an aluminium foil is compounded on a surface A of a paper substrate by virtue of an adhesive layer formed by polypropylene and polyethylene combined composite material, namely the surface A of the paper substrate is externally sequentially compounded with the adhesive layer formed by the polypropylene and polyethylene combined composite material, the plastic film and the aluminium foil to form the waterproof anti-reflection layer; and similarly, a surface B of the paper substrate is compounded with an insulating layer formed by sponge or foam material by virtue of the adhesive layer formed by the polypropylene and polyethylene combined composite material, namely the surface B of the paper substrate is externally sequentially compounded with the adhesive layer formed by the polypropylene and polyethylene combined composite material and the insulating layer. The thermal insulation composite paper container disclosed by the invention can solve the technical problems that a paper container can be filled with liquid and ice cakes and the paper container has thermal insulation, fresh keeping, solid and tear resistance properties.

Description

A kind of insulation extrusion coating paper container that can load bearing fluid

Technical field

The present invention relates to a kind of insulation, antistaling container of papery.

Background technology

Traditional paper container can be made water tumbler after adding watertight composition, but can not have insulation and fresh-keeping function.In addition, the formation of said traditional paper container material is not firm, does not have stronger tear resistance.At present, do not have to satisfy independence or, be used as the contain fluid or the papery large insulation of ice cube, the material of antistaling box as the liner case,

Therefore the purposes of paper container is comparatively single.

Summary of the invention

The purpose of this invention is to provide a kind of insulation extrusion coating paper container that can load bearing fluid, satisfy contain fluid, ice cube, have the technical problem of requirements such as insulation, fresh-keeping and firm anti tear to solve paper container.

In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:

A kind of insulation extrusion coating paper container that can load bearing fluid is formed the cardboard of making container by following layer structure,

Be compounded with the water proof anti-reflection layer that layer of plastic film and aluminium foil are compounded to form at the A of paper substrate plate face through polypropylene mix polyethylene composite adhesive linkage, promptly the A face of cardboard is compounded with polypropylene mix polyethylene composite adhesive linkage, plastic sheeting and aluminium foil outward successively and is compounded to form the water proof anti-reflection layer; Be compounded with the heat-insulation layer that one deck sponge or expanded material form through polypropylene mix polyethylene composite adhesive linkage equally at the B of paper substrate plate face, promptly the B face of cardboard is compounded with polypropylene mix polyethylene composite adhesive linkage and heat-insulation layer outward successively.

The cardboard of said making container is when processing container, and shape moulding as required is in the cardboard jointing positions, through the bonding connection of polypropylene mix polyethylene composite.

Advantage of the present invention is following:

1, have waterproof, insulation, fresh-keeping function simultaneously, can contain fluid or article such as ice;

2, has stronger bearing capacity, anti tear and long service life;

3, can use separately, the liner case that also can be used as common carton uses.

Description of drawings

Fig. 1 is a layer structural representation of the present invention.

The specific embodiment

Concrete structure of the present invention is referring to Fig. 1; The water proof anti-reflection layer 1 that is compounded to form with the material 2 compound layer of plastic film and the aluminium foil of polypropylene PP mix polyethylene PE fusion earlier at the A of paper substrate plate 3 face; Again at material 4 mode composite sponges or the expanded material 5 of the B of paper substrate plate 3 face with identical polypropylene PP mix polyethylene PE fusion; Five layer materials after the completion; Be material composite bed 2, the paper substrate plate 3 of water proof anti-reflection layer 1, polypropylene PP mix polyethylene PE, material composite bed 4 and sponge or the foamed material layer 5 of polypropylene PP mix polyethylene PE; Can either be with the material of the polypropylene PP mix polyethylene PE fusion of first and second layer; The water proof anti-reflection layer that compound layer of plastic film and aluminium foil are compounded to form comes exclusion of water or liquid, can be convenient to folding or shape by die-cutting by the 3rd layer paper substrate plate again, can also intercept the heat conduction by fourth, fifth layer of heat-insulation layer that forms air-saturated hole.The anti-reflection layer that wherein aluminium foil forms has and prevents thermal-radiating function.

Above-mentioned composite be rolling in flakes or can become single sheet by cutting.Box-like through being folded into five or six facial tissues, put into conventional carton as inner bag, with the supporting intensity moulding of carton.Just can be used as waterproof thermal-insulated carton container.

The mode of the combination process of above-mentioned layer structure and polypropylene PP mix polyethylene PE hot melt adhesion and prescription can be referring to the application documents of disclosed CN101701434A invention.At first, make the liquid glue of fusion, the mixture of PP GRANULES and polyethylene particle is warming up to formation fused solution under 280 ℃ to the 330 ℃ high temperature.The mixed weight percentage of the mixture of said PP GRANULES and polyethylene particle is PP GRANULES 70% to 85%, polyethylene 15% to 30%.The fused solution glue of then mixture of above-mentioned PP GRANULES and polyethylene particle being processed, between the compound relatively adhesive surface of the layers of material of rolling, the compound of materials at two layers accomplished in the moment pressing after the showering with every square meter 10 grams to 25 gram showerings.

Plastic sheeting in the A face water proof anti-reflection layer 1 of paper substrate plate 3 can use any plastic material, if PET is used for containing the heat-carrying product, because PET painstakingly bears the high temperature of 400 degree C; If PP or PE can bear the temperature of general 100 degree C; No matter but PET or PP, PE can bear the low temperature of-50 degree.These three kinds of materials all will be food, and the environment-friendly products that medicine can directly contact also can be contained simultaneously and carried the soda acid material, have solved many chemicals, the carrying problem of dangerous material.

What use in the A face water proof anti-reflection layer 1 of paper substrate plate 3 is general aluminizer; If there is the requirement in the use not allow product to contain metal ingredient; So will be at the plastic sheeting back side stamp metal-colored with the mode of printing, this is to utilize the principle that the metal surface can reflected temperature to strengthen heat insulation function.

To sum up, be that the character that basic material is convenient to folding bookbinding and moulding is selected for use with paper; As the surface, can reach the practical use of waterproof while heatproof degree and soda acid with plastic material; Use expanded material to be because the low-density hole in the middle of the material is full of more air, can reach the function of shielding temperature; Using the metal-plated rete also is a kind of reinforcement radiation and convection function, reduces the loss of temperature.
