Problems solved by technology

Hard candies are hard, brittle, amorphous candies that are concentrated from white sugar and starch syrup. This type of candy is characterized by extremely low moisture content, which can easily absorb moisture in the air and cause sand return; Butter candy contains high ingredients of dairy products and fat, and is dispersed in the system as tiny globules. It has a certain hardness at room temperature, but it is easily deformed when heated, and the dispersed fat is easy to spread to the surface of the candy, so the candy is damp or heated. After that, it is easy to adhere to the inner surface of the package, which greatly affects the sales of candies
[0003] Therefore, in addition to moisture-proof, candy packaging materials should also have good heat insulation and anti-sticking effects. Currently, candy packaging on the market basically adopts pillow packaging, but its film materials do not have sufficient performance.

Embodiment Construction

[0012] Combine below figure 1 The technical scheme of the present invention is further described.

[0013] A film for food packaging, comprising a base layer 1, a heat insulating layer 2, a corona layer 7 and an aluminum plating layer 3 are arranged on the top of the base layer 1 in sequence, a heat-sealing layer 4 is arranged below the base layer 1, and a heat-sealing layer 4 is arranged below the heat-sealing layer 4 With sticky rice adhesive layer.

[0014] The glutinous rice adhesive layer is discontinuously and evenly distributed under the heat-sealing layer 4 . The interval between the adjacent glutinous rice adhesive layers exposes the heat-seal layer 4, which is compatible with the sealing of the packaging printing, and the heat-seal layer 4 exposed by the interval between the upper and lower two films is bonded, which is more convenient. The glutinous rice adhesive layer at intervals wraps the candy, which is more reasonable and saves raw materials.

[0015] The gl...

Abstract

The invention provides a thin film for food packaging. The thin film comprises a base layer, wherein a thermal-insulation layer, a corona layer and an aluminum coated layer are sequentially arranged above the base layer; a heat sealing layer is arranged below the base layer; a sticky rice bonding layer is arranged below the heat sealing layer. A product can have good thermal-insulation, damp-proofand anti-sticky properties and is particularly suitable for candy wrapping.

Description

technical field [0001] The invention relates to the field of food packaging, in particular to a film for food packaging. Background technique [0002] Confectionery includes hard candies, cream candies, jelly candies, chocolate products, etc. Hard candies are hard, brittle, amorphous candies that are concentrated from white sugar and starch syrup. This type of candy is characterized by extremely low moisture content, which can easily absorb moisture in the air and cause sand return; Butter candy contains high ingredients of dairy products and fat, and is dispersed in the system as tiny globules. It has a certain hardness at room temperature, but it is easily deformed when heated, and the dispersed fat is easy to spread to the surface of the candy, so the candy is damp or heated. Finally, it is easy to adhere to the inner surface of the package, which greatly affects the sales of candy. [0003] Therefore, in addition to moisture-proof, candy packaging materials should also...
