Description

Technical field:

[0001] The invention relates to a matting film and a manufacturing method thereof, in particular to a biaxially stretched nylon matting film (BOPA matting film for short) and a manufacturing method thereof. Background technique:

[0002] BOPA matting film is a fashionable and high-grade composite and packaging material, which can give people a soft, comfortable and hazy visual effect. After being stimulated by sunlight and screens for a long time, people can eliminate eye fatigue when watching books, pictures, color-printed pictures and packaging compounded with matting film. Moreover, BOPA matting film can be used in food packaging (biscuits, dried fruits, tea, cakes, etc.) after compounding to create an image of a natural product. Corona matting film is suitable for printing, lamination, low-temperature bronzing, etc. It is laminated with paper or other substrates after being glued on the glossy surface. It is usually used for surface lamination of books...
