Abstract
The utility model relates to a novel forming packaging bag easy to uncover. According to the structure, the novel forming packaging bag easy to uncover comprises a packaging bag body and is characterized in that a hot-seal edge on the upper portion of the packaging bag body is of a -type structure, a double-layer non-hot-seal imaginary edge matched with the bag body is arranged on the packaging bag body in the direction of the -type structure, and the width of the non-hot-seal imaginary edge is larger than 5 mm; the structure of the packaging bag body comprises a surface layer, a middle layer, a hot-seal layer, a hot-seal layer, a middle layer and a surface layer in sequence from outside to inside; each surface layer, the corresponding middle layer and the corresponding hot-seal layer are bonded through an adhesive; the two hot-seal layers are sealed through high temperature forming flash melting; each surface layer is a polyamide type thin film, each middle layer is an aluminized barrier basic material; each hot-seal layer is a film which is easy to uncover and is made of polybutylene. Compared with the prior art, the wide non-hot-seal imaginary edge is arranged on an upper seal opening, the upper seal edge is of the -type structure, acting force is concentrated to one point in the pointed portion of a shape, so that the bag is uncovered easily, and manual tearing operation is facilitated.
Description
Technical field
The utility model relates to packaging bag technical field, particularly a kind of novel formed package bag of easily taking off.
Background technology
Food and drug safety wholesomeness life and health direct and people is closely bound up, and selecting suitable packing is one of controlling units that guarantee food and drug quality.In packaging process, the leak tightness of packaging film and easily taking off property directly affect the packing effect of product.Rotten major cause occurs many packing content things is because leak tightness is poor, is subject to that the invasion and attack of moisture and oxygen and microbial physiology metabolism cause.In order to promote the leak tightness of packaging film, often adopt high strength, high heat sealability material, adopt this kind of measure, although the closure of packaging film has improved, it easily takes off poor-performing, is difficult for tearing, in fractionation packaging process, the a large amount of chips of normal generation, sanitation performance is poor, sometimes also can destroy the product of packing the inside.
Summary of the invention
The purpose of this utility model is the technical disadvantages for existing food and Medicine Package Bag, and a kind of novel formed package bag of easily taking off is provided.
The utility model is achieved through the following technical solutions:
A kind of novel formed package bag of easily taking off, structure comprises packaging bag main body (A), it is characterized in that, described packaging bag main body (A) top hot edge seal is set to "∧" type structure (A1), packaging bag main body (A) is provided with along "∧" type structure (A1) direction the bilayer coordinating with bag and does not seal empty limit (A2), does not seal empty limit (A2) width and is greater than 5mm.
Further, described packaging bag main body (A) structure comprises top layer (1) that ecto-entad distributes successively, interlayer (2), hot sealing layer (3), hot sealing layer (3), interlayer (2) and top layer (1).
Further, described connected top layer (1), interlayer (2) and hot sealing layer (3) successively binds by adhesion agent.
Further, described hot sealing layer (3) passes through high-temperature molding thermosol involution with hot sealing layer (3).
Further, described top layer (1) is polyamide type film.
Further, described interlayer (2) is the type barrier base material of aluminizing.
Further, described hot sealing layer (3) is easily taken off film for what contain polybutene.
The utility model relates to a kind of novel formed package bag of easily taking off, and beneficial effect is:
1. the novel formed package bag of easily taking off that the utility model relates to, upper sealing leaves the empty limit of wider not heat-sealing, and upper edge sealing is set to "∧" type structure, and "∧" type shape sharp-crested place can make force localization in a bit, thereby make sack be more prone to open, be convenient to the manual operation of tearing.
2. the novel formed package bag of easily taking off that the utility model relates to, hot sealing layer adopt contain polybutene easily take off membrane material, reduce to a certain extent the heat sealability of packaging film, the performance of easily taking off of product is further promoted, when meeting leak tightness, improved easily the taking off property of product.
Accompanying drawing explanation
Fig. 1 is the novel formed package bag structural representation of easily taking off that the utility model relates to.
Fig. 2 is the novel formed package bag cross-sectional view of easily taking off that the utility model relates to.
The specific embodiment
Consulting accompanying drawing 1 and Fig. 2 is described further the utility model.
As shown in the figure, the utility model relates to a kind of novel formed package bag of easily taking off, structure comprises packaging bag main body (A), it is characterized in that, described packaging bag main body (A) top hot edge seal is set to "∧" type structure (A1), packaging bag main body (A) is provided with along "∧" type structure (A1) direction the bilayer coordinating with bag and does not seal empty limit (A2), does not seal empty limit (A2) width and is greater than 5mm.
As shown in Figure 2, described packaging bag main body (A) structure comprises top layer (1) that ecto-entad distributes successively, interlayer (2), hot sealing layer (3), hot sealing layer (3), interlayer (2) and top layer (1).
Described connected top layer (1), interlayer (2) and hot sealing layer (3) successively binds by adhesion agent.
Described hot sealing layer (3) passes through high-temperature molding thermosol involution with hot sealing layer (3).
Described top layer (1) is polyamide type film.
Described interlayer (2) is the type barrier base material of aluminizing.
Described hot sealing layer (3) is easily taken off film for what contain polybutene.
The novel formed package bag of easily taking off that the utility model relates to, upper sealing leaves the empty limit of wider not heat-sealing, and upper edge sealing is set to "∧" type structure, and "∧" type shape sharp-crested place can make force localization in a bit, thereby make sack be more prone to open, be convenient to the manual operation of tearing; Hot sealing layer adopt contain polybutene easily take off membrane material, reduced to a certain extent the heat sealability of packaging film, the performance of easily taking off of product is further promoted, when meeting leak tightness, improved easily the taking off property of product.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
