Abstract
The invention discloses a food packing bag and a production method thereof. The food packing bag comprises a packing bag body, wherein the upper end of the packing bag is a sealing end and is provided with a tear line for tearing off a packing bag opening; the packing bag is an integral film which is transparent on one side and non-transparent on the other side; the transparent side is a transparent film; the non-transparent side is an aluminized film; the food bag is produced through film blowing, cutting, aluminum plating, compounding and bagging. The two sides of the packing bag are arranged to be the transparent and non-transparent films respectively, so that foods can be prevented from being irradiated by sunlight after being packed, and a client can also intuitively feel a commodity.
Description
Technical field
The present invention relates to packaging field, specifically a kind of food pack and production method thereof.
Background technology
On the fairgrounds such as supermarket, commodity are all be placed on show-case by packaging bag at present, and in order to the outward appearance making client can see commodity, conventional packing bag is all use hyaline membrane to make, and client is just by the outward appearance seeing commodity of hyaline membrane subjectivity.
For food commodity, because its shelf-life is short, storage requirements is high, and some food produces chemical reaction after solar radiation, quality is declined can not use, in order to avoid food spoilage, some food is just packed with the packaging film of all aluminizing, but this packaging will make client can not see food intuitively, sales volume will decline, therefore need a kind of food pack, food can be avoided to by sunlight, can allow again client's direct feel commodity.
Summary of the invention
The object of the present invention is to provide a kind of food pack and production method thereof, food after making food packaged, can be avoided to by sunlight, can allow again client's direct feel commodity.
Object of the present invention can be achieved through the following technical solutions:
A kind of food pack, comprise packaging bag body, packaging bag upper end is sealing end, the upper end of packaging bag be provided with tear packaging sack tear line, the as a whole film of described packaging bag, side is transparent, opposite side is opaque, and transparent side is hyaline membrane, and opaque side is aluminizer.
Further, packaging bag upper end is also provided with and wears mouth, wears mouth and is arranged in the middle of upper end, wear mouthful length be packaging bag wide 2/3rds.
A production method for food pack, described production technology is as follows:
(1) blown film, blows out film be wound on roller by inflation film manufacturing machine by film raw material;
(2) cut, the film dividing of support is become to need the film of width;
(3) aluminize, by aluminum-spraying machine, hyaline membrane is aluminized, make hyaline membrane opaque;
(4) compound, is compounded in hyaline membrane and aluminizer on basement membrane by compounding machine simultaneously, generates mandarin duck film;
(5) bag, it is transparent mandarin duck film to be made side, the opaque packaging bag of opposite side.
Beneficial effect of the present invention: the both sides of packaging bag are set to transparent and opaque film by the present invention respectively, can avoid food to by sunlight after making food packaged, can allow again client's direct feel commodity.
