Description

Packaging paper for frozen food

Technical Field

The utility model belongs to the technical field of the packing and the transportation of cold-stored food, a frozen food is with packing note paper is related to.

Background

The packaging of frozen food products is an important process in the transportation process. At present, when frozen food is packaged and transported, a foam box or a corrugated carton is generally adopted, but the defects of the foam box or the corrugated carton are obvious: 1. the foam box has higher recovery cost and is easy to cause environmental pollution; 2. corrugated containers, although easily recyclable, do not have waterproof and moisture-proof properties and are easily damaged during transportation, particularly when transporting food items that require cold-temperature storage and transportation, such as: transporting seafood. The two types of packaging paper of the prior art mentioned above are very inconvenient for food to be transported in cold or warm conditions.

To sum up, for solving the technical not enough of current packing carton, the utility model designs a simple structure, be applicable to the packing of frozen food, convenient transportation, the good packing note paper for frozen food of heat-retaining ability.

Disclosure of Invention

The utility model provides a packaging paper for frozen food with simple structure, good packaging, convenient transportation and heat preservation, which is suitable for frozen food.

The purpose of the utility model can be realized by the following technical proposal:

a packaging paper for frozen food, comprising:

the first surface layer comprises a first aluminum foil layer and a first paper layer which are sequentially arranged from top to bottom;

the middle layer is a composite corrugated paper layer and comprises a corrugated paper layer I, an isolation layer and a corrugated paper layer II which are sequentially arranged;

the second surface layer comprises a second paper layer and a second aluminum foil layer which are sequentially arranged from top to bottom.

As a further improvement of the scheme, the isolation layer is a PE film layer.

As a further improvement of this solution, the first aluminum foil layer and the first paper layer are bonded by glue.

As a further improvement of this solution, the second paper layer and the second aluminum foil layer are bonded by glue.

As a further improvement of the scheme, the first corrugated paper layer and the second corrugated paper layer are three or five layers.

Compared with the prior art, the utility model discloses the structure sets up rationally, and through the setting of first surface course and second surface course, first aluminium foil layer and second aluminium foil layer make the overall structure of wrapping paper possess dampproofing and waterproofing's characteristics on, are difficult to damage in the transportation, need the food that cold temperature preserved to the transportation, and the effect is good. The first aluminum foil layer and the second aluminum foil layer have the waterproof and heat-insulating effects, so that the packaging box can be used as a refrigerator for placing foods such as live crabs and seafood.

Fig. 2 is a schematic diagram of the structure of the middle layer of the present invention.

In the figure, 10 — first facing; 11-a first aluminium foil layer; 12-a first paper layer; 20-an intermediate layer; 21-corrugated paper layer one; 22-an isolation layer; 23-a second corrugated paper layer; 30-a second facing; 32-a second paper layer; 31-second aluminium foil layer.

Detailed Description

The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.

As shown in fig. 1 to 2, the paper for packaging frozen food comprises, in order:

a first surface layer 10, which comprises a first aluminum foil layer 11 and a first paper layer 12 arranged from top to bottom in sequence;

the middle layer 20 is arranged in a wave shape, is a composite corrugated paper layer and comprises a first corrugated paper layer 21, an isolation layer 22 and a second corrugated paper layer 23 which are sequentially arranged;

the second surface layer 30 includes a second paper layer 32 and a second aluminum foil layer 31 sequentially arranged from top to bottom.

Therefore, the utility model discloses a frozen food is with packing paper, through the setting of first surface course 10 and second surface course 30, first aluminium foil layer 11 and second aluminium foil layer 31 make the overall structure of wrapping paper possess dampproofing and waterproofing's characteristics on, are difficult to damage in the transportation, need the food that cold temperature was preserved to the transportation, and the effect is good. The first aluminum foil layer 11 and the second aluminum foil layer 31 have the waterproof and heat-insulating effects, so that the packaging box can be used as a refrigerator for placing foods such as live crabs and seafood.

Compare current foam case, inconvenient during the transportation can warp even under certain pressure, and is cracked, finally influences holistic heat preservation effect.

Specifically, the overall structure and the material of the packaging paper are environment-friendly and low in cost compared with foam materials. The middle layer 20 is in a wave-shaped design, so that the structure of the packaging paper is stable. Set gradually corrugated paper layer 21, isolation layer 22 and corrugated paper layer two 23 through the intermediate level, further make the heat preservation effect of packing paper good, also further prevent that packing paper from being impaled by sharp object and leading to the damage, the influence is used.

Comparative example 1 the middle layer was only one corrugated paper layer, which was prepared into a carton.

Comparative example 2 the middle layer was a double-ply corrugated paper layer, which was prepared into a carton.

Sample 1 was a paper for packaging frozen food in this example, and the intermediate layer was a composite corrugated paper layer, which was prepared into a carton.

TABLE 1 refrigeration and sealing Properties

As shown in table 1, the paper for packaging frozen food of the present example is excellent in refrigerating and sealing properties, and after the ice pack is put in, a little crushed ice remains after 48 hours, and thus it can be suitably used for long-distance refrigerated transport, and is comparable to the paper packaging box of the prior art.

In the specific preparation, the first aluminum foil layer 11 and the first paper layer 12 are bonded by glue, and the second paper layer 32 and the second aluminum foil layer 31 are bonded by glue.

As a further preferred embodiment, the barrier layer 22 is a PE film layer.

In the embodiment, the isolation layer 22 is a plastic film layer, specifically a PE film, which enables the thermal insulation performance of the paper for packaging frozen food to be good and can effectively prevent piercing when a sharp object is packaged.

As a further preferred embodiment, the first aluminium foil layer 11 is glued to the first paper layer 12 by means of glue.

As a further preferred embodiment, the second paper layer 32 and the second aluminium foil layer 31 are glued together by means of glue.

More specifically, the glue is an LDPE layer, and the low density polyethylene has a strong viscosity when melted, so that the first aluminum foil layer 11 and the first paper layer 12 can be stably bonded. Of course, the adhesive layer may also be the remaining type of adhesive.

As a further preferred embodiment, the first corrugated paper layer 21 and the second corrugated paper layer 23 are three or five layers.

In this embodiment, the first corrugated paper layer 21 and the second corrugated paper layer 23 are provided with three or five layers, so that the overall heat insulation performance is good.

The aluminum foil layer of the packaging paper for frozen food can be printed as required, and the packaging paper plays a role in marking.

The preferred embodiments of the present invention are described herein, but the scope of the present invention is not limited thereto. Modifications or additions to or replacement by similar means to those skilled in the art to which the invention pertains to the specific embodiments described herein are intended to be covered by the scope of the invention.
