Abstract

The utility model discloses paper used for producing paper cups and paper bowls, which comprises a raw paper layer and a film coating layer. The innovative point of the utility model lies in that the raw paper layer comprises a bleached fiber layer and a non-bleached fiber layer, wherein the non-bleached fiber layer adopts an unbleached woody fiber layer or vegetable fiber layer. The paper used for producing paper cups and paper bowls adopting the structure has the advantages of environmental protection, hygiene, good stiffness and folding resistance, etc.

Description

Be used to make the paper of cup paper bowl

Technical field

The utility model belongs to the Food Packaging technology field, is specifically related to a kind of paper that is used to make the cup paper bowl.

Background technology

At present, be used to make the paper of cup paper bowl in the prior art, it comprises original paper layer and leaching membrane layer, and in order to increase print gloss and image color effect, it can also comprise coating layer.Described original paper layer generally all adopts bleached wood fiber or bleaching string and bleached mechanical pulp (BCTMP) to manufacture paper with pulp and forms, and we are referred to as the bleached fiber layer by system this original paper layer.The simple bleached fiber layer that adopts is that paper that original paper layer is used to make the cup paper bowl has deflection and folding strength is poor.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides good being used to of a kind of environmental protection, health, deflection and folding strength to make the paper of cup paper bowl.

The technical solution of the utility model is achieved in that a kind of paper that is used to make the cup paper bowl, it comprises original paper layer and leaching membrane layer, it is characterized in that: described original paper layer comprises non-bleached fiber layer, and described non-bleached fiber layer is wood fibre or the plant fiber layer without bleaching.

Described original paper layer comprises bleached fiber layer and non-bleached fiber layer, and permutation and combination method is bleached fiber layer+non-bleached fiber layer or bleached fiber layer+non-bleached fiber layer+bleached fiber layer preferably.

Described non-bleached fiber layer comprises the non-bleached fiber layer of the true qualities of being made by true qualities wood fibre or string and by wood fibre that adds pigment or the colored non-bleached fiber layer that string is made.

In order to increase print gloss and image color effect, described original paper layer also comprises coating layer.

Described leaching membrane layer comprises two types, and a kind of is coloured polyethylene (LDPE) layer of additive color mother, and a kind of is not additive color mother's transparent polyethylene (LDPE) layer.

The utility model compared with prior art has following advantage: described original paper layer comprises bleached fiber layer and non-bleached fiber layer, because without bleached wood fiber or string, relatively have a water resisting property with the paper and the paperboard class of other homogeneities, environmental protection, health, deflection and the good advantage of folding strength, so adopt the paper that is used to make the cup paper bowl of this structure, have advantages such as environmental protection, health, deflection and folding strength are good.
