Embodiment Construction

[0007] Structure of the present invention sees figure 1 , its layer structure is the upper paper layer 1, polypropylene and polyethylene fusion bonding layer 2, PET or OPP or PVC or plastic braided cloth reinforcement layer 3, polypropylene and polyethylene fusion bonding layer 4 and the lower paper layer 5.

[0008] The upper paper layer 1 is bonded with PET or OPP or PVC or plastic woven cloth reinforcing layer 3, PET or OPP or PVC or plastic woven cloth reinforcing layer 3 is bonded with lower paper layer 1 through adhesive layers 2 and 4, and the adhesive layer 2 and 4 are composed of polypropylene and polyethylene melt adhesives as bonding materials after being melted at high temperature.

[0009] When the reinforcing layer is PET, the bonding of polypropylene and polyethylene melt adhesive is best at the melting temperature of 380°C-400°C.

[0010] When the reinforcing layer is OPP, the bonding of polypropylene and polyethylene melt adhesive is best when the melting te...

Abstract

The invention discloses novel reinforced composite paper. A layer structure of the novel reinforced composite paper comprises an upper paper layer, a polypropylene and polyethylene fusing and bonding layer, a PET (Polyester) or OPP (Oriented Polypropylene) or PVC (Polyvinyl Chloride) or plastic woven cloth enhanced layer, a polypropylene and polyethylene fusing and bonding layer and a lower paper layer. The invention can solve the technical problems of poor obdurability, moisture and water proofing, and the like of the traditional paper.

Description

technical field [0001] The present invention relates to a new and improved paper structure. Background technique [0002] Traditional paper is made of pure paper, which has low ring pressure index and burst index, and does not have the function of moisture-proof and water-proof. In the production of cartons, in order to change the above shortcomings, in the past technical solutions, waterproof or moisture-resistant agents are often added to the paper surface, so the paper itself has moisture-resistant and waterproof functions, but it is difficult to process or paste other paper. Can be difficult, or difficult to use cheap binders such as starch. Contents of the invention [0003] The purpose of the present invention is to provide a new type of strengthened composite paper to solve the technical problems of poor toughness, non-moisture-proof and water-proof existing in traditional paper. [0004] The layer structure of a kind of novel reinforced composite paper of the pre...
