Embodiment 1

[0018] Example 1: Two rolls of paper-plastic composite film are pressed into a strip-shaped double-layer composite film with one side sealed on the film compound machine. The pressing temperature is 128 ° C, and the width of the composite film is 3 cm. Press a short edge of the composite film, which is perpendicular to the above-mentioned pressed long side edge; put the composite film with two vertical edges on the packaging machine, and the unsealed side of the double-layer composite film One side is stretched; add biscuits to be packaged in the above-mentioned stretched double-layer composite film; seal one of the unsealed two sides; seal the composite film with three sides in a bag Vacuum the inside of the container first, then fill it with inert gas nitrogen, and the pressure of the inflation is 3 atmospheres; then seal the last side to obtain a packaged packaging bag filled with materials. After 12 months of packaging, the dryness of the packaging bag is 82% of that at th...

Embodiment 2

[0019] Example 2: Two rolls of paper-plastic composite film are pressed into a strip-shaped double-layer composite film with one side sealed on a film compounding machine. The pressing temperature is 155° C., and the width of the composite film is 6 cm. Press a short edge of the composite film, which is perpendicular to the above-mentioned pressed long side edge; put the composite film with two vertical edges on the packaging machine, and the unsealed side of the double-layer composite film One side is stretched; add the tea leaves to be packaged in the stretched double-layer composite film; seal one of the unsealed two sides; seal the composite film with three sides in a bag Vacuum the inside of the container first, then fill it with inert gas nitrogen, and the pressure of the inflation is 5 atmospheres; then seal the last side to obtain a packaged packaging bag filled with materials. After 12 months of packaging, the dryness of the packaging bag is 95% of that at the factory...

Embodiment 3

[0020] Example 3: Press two rolls of paper-plastic composite film on a film laminating machine to form a strip-shaped double-layer composite film with one side sealed. The pressing temperature is 170° C., and the width of the composite film is 12 cm. Press a short edge banding of the composite film, which is perpendicular to the long side banding of the above-mentioned pressing; put the composite film with two vertical side bands on the packaging machine, and the unsealed side of the double-layer composite film One side is stretched; add melon seeds to be packaged in the above-mentioned stretched double-layer composite film; seal one of the two unsealed sides; seal the composite film with three sides in a bag Vacuum the inside of the container first, then fill it with inert gas nitrogen, and the inflation pressure is 4 atmospheres; then seal the last side to obtain a packaged packaging bag filled with materials. After 12 months of packaging, the drying degree of this packaging...

Abstract

The invention belongs to the technical field of packing, in particular to a food packing method. The food packing method comprises the following steps: two rolls of films are pressed to form a strip-shaped two-layer composite film with a sealed side edge on a film compounding machine; the composite film is pressed with a short sealed edge on the film compounding machine, and the sealed edge is perpendicular to the sealed side edge; the composite film pressed with two perpendicular sealed edges is placed on a packing machine, and the unsealed side of the two-layer composite film is supported; a material to be packed is added into the supported two-layer composite film; one of the two unsealed side edges is sealed; the composite film with three sealed edges is vacuumized in a bag forming machine, and inert gas is charged; and the last side edge is sealed. The food packing method has the beneficial effects of beautiful sealed edges of obtained packing bags, difficult generation of running through phenomenon, quick packing speed, capability of keeping substances in the bags from being oxidized for a long time, prolonging of the shelf life of packing materials and preferable guarantee of product quality.

Description

technical field [0001] The invention belongs to the technical field of packaging, in particular to a food packaging method. Background technique [0002] The packaging machine is a machine for packaging products, which plays the role of protection and beauty. The packaging process does not affect the quality of the packaging, but can shrink quickly and perfectly. The packaged products can be sealed, moisture-proof, and impact-proof. With the continuous improvement of people's living standards, the demand for various convenience foods has also increased greatly, which has further stimulated the rapid development of my country's packaging industry. There are many small packaging companies in our country, most of them are manually bagged and sealed, the speed is difficult to control, and it will cause secondary pollution of food. [0003] With the continuous development of science and technology, food is now mostly packaged by machines, and food in small packages has been grea...
