In order to obtain the barrier performance to water, oil, etc., a plastic film (coating) needs to be laminated on the original paper, and most of them are polyethylene (PE) laminated film in the market, but PE laminated film products have the disadvantages of being hard to degrade, non-repulpable and difficult to recycle.
In order to overcome these shortcomings, R&D personnel are constantly trying to find more suitable alternatives or processes. Various kinds of waterproof and oil-proof packaging paper have emerged in the market, among which water-based coating paper is one of the highlights. The basic principle of coating: the use of coating compounding equipment, organic degradable molecular materials covered on top of the paper, the use of organic degradable molecular materials, the perfect filling of the paper surface originally pitted small gaps, so that the paper coating surface to achieve a smooth and flat, intermolecular fibers and paper fibers to get connected, so that the paper and the coating closely combined to form a waterproof / oil-proof degradable film layer. It can replace the original plastic coated laminated products and replace the plastic with paper by meeting the customer's needs and subsequent production and use of the product.
Water-based coating paper has a variety of advantages and can replace traditional plastic laminated products, and is widely used in various fields such as paper packaging for food products, cold chain packaging for food, paper packaging for household chemicals, paper packaging for toys and paper soft packaging for medical supplies.
Compared with PE laminated paper, PE laminated paper is not recyclable and non-degradable, which will cause great pressure on the ecological environment, while water-based coating coated paper has the characteristics of re-pulpable, recyclable and degradable, which is more conducive to reducing carbon emissions.

Compared with PLA laminated paper, although PLA laminated paper is also degradable and compostable, the degradability of PLA laminated paper is not as good as water-based coating coated paper, and PLA laminated paper is difficult to recycle and reuse, which causes waste of resources.
