Problems solved by technology

[0002] Ordinary desiccant packaging paper is granular silica gel particle packaging paper, coated composite paper, which can be punched when air permeability is required. The diameter of silica gel particles is about 2mm, and the pinhole is 0.1-0.5mm, so it will not leak out. However, when powder raw materials (lime, iron powder) are loaded, powder will definitely leak, which will affect product safety. Therefore, we have proposed a food-grade powder packaging paper to solve the above problems

Embodiment 1

[0022] Refer Figure 1-4 A food grade powder brown paper, including the upper body 25, and the bottom body 25 is fixedly coupled to the body 20, and the upper body 25 and the lower body 20 are integrally formed, and the top body 25 and the lower body 20 are commonly provided. The lower bib 18, the upper body 25 and the lower body 20 together constitute the body of the wrapper, and the folding is folded by the lower beam 18, which is convenient to turn over the surface of the upper body 25 and the lower body 20 surface.

[0023] In the present invention, both body 25 and the lower body 20 are composed of PET film 1, white original paper liner 5, polyethylene PE film 6, and two dedicated adhesive glue 4, and PET film 1 is a relatively comprehensive performance. Packing film, has a good transparency, gloss, good airtight, fragrant and moisture-proof sexuality, excellent mechanical properties of PET film 1, strong toughness is the best, toughness and resistance in all thermoplastics Th...

Embodiment 2

[0031] Refer Figure 1-4 A food grade powder brown paper, including the upper body 25, and the bottom body 25 is fixedly coupled to the body 20, and the upper body 25 and the lower body 20 are integrally formed, and the top body 25 and the lower body 20 are commonly provided. The lower bib 18, the upper body 25 and the lower body 20 together constitute the body of the wrapper, and the folding is folded by the lower beam 18, which is convenient to turn over the surface of the upper body 25 and the lower body 20 surface.

[0032]In the present invention, the upper body 25 and lower body 20 by a PET film, a white paper mount 5, 6 and two polyethylene PE film 4 composed special adhesive glue, the PET film 1 is a more comprehensive performance packaging film, good transparency, gloss, has good air tightness, moisture resistance and aroma preservation, excellent mechanical properties of the PET film 1, the strength and toughness is best for all thermoplastics, tensile strength and resist...

Abstract

The invention discloses food-grade powder packaging paper which comprises an upper body. The bottom of the upper body is fixedly connected with a lower body, the upper body and the lower body are integrally formed, and a lower fold is jointly arranged between the upper body and the lower body; and the upper body and the lower body are composed of a PET film, white base paper lining paper, a polyethylene PE film and two pieces of special adhesive glue, a plurality of round holes are formed in the PET film, and the two pieces of special adhesive glue are coated at the two sides of the white base paper lining paper respectively. By means of the food-grade powder packaging paper, depending on high air permeability of the white base paper lining paper, the dust leakage is blocked, the high tensile strength of the PET film and the heat sealability of the PE film are used, the three performances are combined together to manufacture the food-grade powder packaging paper, the market prospect is wide, application is wide, and the food-grade powder packaging paper can be suitable for packaging more than 90% of drying agents, deoxidizing agents, preservatives, ripening agents and the like.

Description

Technical field [0001] The present invention relates to the field of powder packaging paper, in particular, to a food grade powder wrapper. Background technique [0002] Ordinary desiccant wrapper is granular silica gel particles package paper, the granule composite paper, the needle can be punched, the silica gel particles are about 2 mm, so that the pinhole is 0.1-0.5mm, so it will not leak, However, when weapping powder material (lime, iron powder) will definitely leak powder, affect product safety, for this, we propose a food grade powder wrapper to solve the above problems. Inventive content [0003] It is an object of the present invention to solve the disadvantages of the prior art, and a food grade powder package proposed. [0004] In order to achieve the above object, the present invention adopts the following technical solution: [0005] A food grade powder wrapper, including upper body, the bottom of the upper body fixedly coupled to the body, the upper body and the l...
