Abstract

The invention provides a drier coating film-nonwoven paper. The invention is characterized in that the drier coating film is prepared by the following steps: preparing heat sealable tea filter paper from natural plants and natural plants with high-polymer plastic fiber, and carrying out hot press compounding with a high-polymer plastic spunbonded nonwoven fabric to obtain the drier coating film. The drier coating film has the advantages of high strength and higher dust resistance, and can adapt to production of automatic high-speed production equipment.

Description

technical field [0001] The invention relates to the technical field of composite packaging materials, in particular to a novel desiccant coating film. Background technique [0002] The packaging material used as a desiccant must have the following properties: the material must have sufficient mechanical strength, be breathable, not leak, can be directly heat-sealed to adapt to automatic packaging machinery, and can be printed and other processing properties. [0003] Nowadays, heat-sealed tea filter paper (abbreviation: Guotou paper) and PET spunbond non-woven fabric (abbreviation: domestic non-woven fabric) are commonly used as desiccant packaging materials. The main composition of Guotou paper is natural plant fiber, and its main defects are The strength of the material itself is not high, and the heat sealing strength is poor; the main components of domestic non-woven fabrics are polyethylene terephthalate (PET for short) and polypropylene (PP) or polyethylene (PE). The m...
