Problems solved by technology

[0004] In polyethylene coated paper and coated release paper, due to the thickness and compatibility of the polyethylene coated film, the PE layer cannot always have good adhesion to the substrate, that is, the paper, and it is easy to peel off during production. and cause production interruption, or produce peeling in actual use
This problem has not been solved in the industry. Burning base paper or corona to eliminate surface impurities is often used to improve the adhesion of plastic and paper. However, due to the similar compatibility of plastic and paper, it has little effect
In addition, flame burning and high-voltage corona are added to the production, the auxiliary equipment is expensive, and the production is unsafe and prone to fire

Embodiment 1

[0017] Embodiment 1: a kind of new structure single-sided coated paper 1 (also can be referred to as single plastic paper), as figure 1 As shown, the base paper layer 1A has two opposite surfaces, the adhesive layer 1B has one layer and is positioned on one surface of the base paper layer, the coating layer 1C has one layer and is positioned on the adhesive layer, and the adhesive layer 1B Adhere one surface of the base paper layer 1A and the coating layer 1C.

[0018] Wherein, the adhesive layer is a water-based (emulsion) polyolefin coating layer, such as a water-based (emulsion) polyethylene coating layer or a water-based (emulsion) polypropylene coating layer. The thickness of the water-based polyolefin coating layer is 1-10 μm (the weight generally ranges from 1 gram to 10 grams per square meter).

[0019] Wherein, the coating layer is a polyethylene coating layer or a polypropylene coating layer. The thickness of the coating layer is 15-25 μm (the weight generally rang...

Embodiment 2

[0024] Embodiment 2: a kind of new structure double-sided coated paper 2 (also can be referred to as double plastic paper), as figure 2 As shown, the base paper layer 2A has two opposite surfaces and is respectively the first and second surfaces 2A1 and 2A2, and the adhesive layer has two layers and is respectively the first and second adhesive layers 2B1 and 2B2, and the first and second adhesive layers 2B1 and 2B2 are located on the first and second surfaces 2A1 and 2A2 of the base paper layer respectively, the coating layer has two layers and are respectively the first and second coating layers 2C1 and 2C2, and the first and second coating layers 2C1 and 2C2 Located on the first and second adhesive layers 2B1 and 2B2 respectively, the first adhesive layer 2B1 is bonded to the first surface 2A1 of the base paper layer and the first coating layer 2C1, and the second adhesive layer 2B2 is bonded to the The second surface 2A2 of the base paper layer and the second coating laye...

Abstract

The invention discloses plastic coated paper having novel structure, which comprises a base paper layer, at least one coating layer, and an adhesive layer disposed therebetween. The adhesive layer is an aqueous polyolefin coating layer. The similar compatibility of the adhesive layer is between that of paper and plastic, so it can bond the base paper layer and the coating layer, to effectively avoid stripping of the base paper layer and the coating layer. The plastic coated paper can be widely applied as office paper, food packing paper, food container and other packing paper for moisture protection and leakage protection, or used to produce release paper in industries of adhesive tape, advertisement, and self adhesive.

Description

technical field [0001] The invention belongs to the field of composite paper, and mainly relates to a coated paper with a new structure. Background technique [0002] Release paper, also known as silicone oil paper and anti-stick paper, can be divided into three categories according to raw materials: glassine release paper, polyethylene coated release paper (PEK) and kaolin coated release paper. Among them, polyethylene coated release paper is mass-produced in China because of its dimensional stability and other advantages, and is widely used in tapes, advertising and other industries. [0003] Laminated paper is a composite paper that uses paper as a substrate and adopts a special process to attach PE (polyethylene) and PP (polypropylene) plastics to it. Generally used for waterproof and leak-proof food containers, wrapping paper and various moisture-proof papers. Polyolefin (including PE and PP) coated paper in coated paper is widely used because of its good anti-adhesiv...
