Silver reflective plastic film bag, and processing method and application thereof

Abstract

The invention discloses a silver reflective plastic film bag and its processing method and application; the silver reflective plastic film bag can be used as a fruit bag, and has very good strength and heat insulation effect, and protects the fruit from harm. Keep the fruit growing environment stable. A silver reflective plastic film bag disclosed by the invention comprises a bag body with an opening; a base layer and a reflective layer coated on the base layer; the reflective layer is an aluminized reflective layer; the base layer is made of a hydrophobic material The reflective layer is a reflective film; the reflective film is followed by an inner layer of hot melt adhesive film layer for bonding with the base layer, a middle layer of glass beads layer and an outer layer of aluminum-coated plastic along the direction away from the base layer. film; the material of the hot melt adhesive film is EVA or maleic anhydride grafted polyethylene or a mixture of the two, and the VA content in the EVA resin is 5% to 40%; in the maleic anhydride grafted polyethylene, the grafted The rate is 0.5% to 0.8%, and the Vicat softening point is above 110°C.

Description

technical field [0001] The invention belongs to the technical field of fruit bagging, and in particular relates to a fruit bagging method and application thereof. Background technique [0002] Bagging materials and methods are directly related to the quality, yield and harvesting period of the fruit; old newspaper bags and kraft paper bags are commonly used for bagging in loquat production, but these two bagging materials are not resistant to moisture and are easy to become soft when exposed to rain. Afterwards, the bag wall was tightly attached to the loquat fruit, and the sun was shining on sunny days, and the fruit was damaged by sunburn. In recent years, the restoration of the ecological environment has caused a large number of birds to multiply, and the bird damage in mountainous loquat gardens is very serious. If the bag becomes soft, the birds can peck the bag. Bags harm fruit. Contents of the invention [0003] The technical problem to be solved by the present inv...
