Description

Bactericidal fresh-keeping liquid bagged food structure

The present invention relates to the technical field of aseptic packaging liquid bag food, in particular to a sterilization fresh-keeping liquid bagged food structure.

Modern medical technology has improved the standard of living. People generally have the concept of health care. In addition to using diet to reduce the incidence of diseases, they also use health foods to enhance immunity and keep the body healthy. There are many types of health foods on the surface. The most common ones are sealed with aluminum foil sealed bags. Users must first tear open the aluminum foil sealed bag to eat.

The conventionally known aluminum foil sealed bags are generally simply laminated with two sheets of aluminum foil film, and heat sealed to form a closed space for sealing and packaging health food. Although the hot pressing sealing process is convenient, the packaging can only be used. Provides the most basic sealing and anti-lighting effects.

However, its practicality does not provide the best preservation of the freshness, can not effectively prevent the deterioration of the contents, and the safety and health needs of high temperature sterilization at the same time in the packaging process. As a result, for some high-end health foods, such as high-concentration Chinese medicines, etc., the packaging effect is still not perfect, it is necessary to improve.

In view of this, the main purpose of this creation is to provide a sterilized fresh-keeping liquid packaged food structure, including:

The outer side of the bag body is provided with an edge seal, and the inner bag has a chamber;

a pre-shearing opening is disposed on a side of the bag body for tearing the bag body, and;

a Chinese medicine health liquid is filled in the chamber to form a sealed package;

It is characterized by:

The bag body is a composite layer soft bag for high temperature sterilization, and has at least a first layer, a second layer and a third layer, wherein the first layer, the second layer and the third layer are respectively different Material composition

The first layer is the outermost layer, and preferably is composed of a single OPP polypropylene film;

The second layer is an intermediate layer which is a composite film. Preferably, the upper layer is a PET thermoplastic polyester resin film, the middle interlayer is an AL aluminum film, and the lowermost layer is a NY unstretched polyamide film. ,as well as;

The third layer is the innermost layer and is preferably constructed from a single CPP cast polypropylene film.

Thereby, the thickness of the material of the bag body can be determined according to the content of the product or the demand of the customized product, and the glue of each layer can also be adjusted according to the sterilization temperature of the process.

Compared with the prior art, the biggest advantage of the creation bag is that it can reduce the variation of the inner package items when applied, and is most suitable for holding some high-grade health foods. For example, traditional Chinese medicine health care liquid, etc., can achieve the practical purpose of preserving the original taste and locking the essence.

In order to facilitate the understanding of the purpose, shape, structural composition and function of this creation, we will further understand and understand the following examples.

Please refer to Fig. 1 to Fig. 4, the food structure of the sterilization fresh-keeping liquid bag set in this creation mainly includes:

a bag body 1 is provided with an edge seal 11 on the outside, and an inner chamber has a chamber 10;

a pre-tear 12 is disposed on the side of the bag body 1 for tearing the bag body 1 and;

a Chinese medicine health liquid 2 is filled in the chamber 10 to form a sealed package;

It is characterized by:

The bag body 1 is a composite layer soft bag for high temperature sterilization, and has at least a first layer 101, a second layer 102, and a third layer 103, and the first layer 101, the second layer 102, and The third layer 103 is composed of different materials, wherein

The first layer 101 is the outermost layer, and preferably is composed of a single OPP polypropylene film;

The second layer 102 is an intermediate layer which is a composite film. Preferably, an uppermost layer 1021 is a PET thermoplastic polyester resin film, a middle interlayer 1022 is an AL aluminum film, and a lowermost layer 1023 is a NY unstretched polyfluorene. Amine film, and;

The third layer 103 is the innermost layer and is preferably constructed of a single CPP cast polypropylene film.

Preferably, the first layer 101, the second layer 102, and the third layer 103 are further provided with a heat-resistant adhesive 100 that can withstand 100 ° C or higher.

Preferably, the shape of the bag body 1 is not particularly limited. As shown in Figures 3 and 4, the edge seal 11 of the bag body 1 further has an upper edge 111 and a bottom edge 112. And the two sides of the sealing edge 113 are formed, and a pre-tearing opening 12 is provided at an upper sealing edge of the one side sealing edge 113 so that the user can tear the bag body 1 from the pre-shearing opening 12. Or as shown in Figures 5 and 6, wherein the bag body 1 can also be provided with the same upper sealing edge 111 and lower sealing edge 111' to provide the use effect of different types of packaging.

Preferably, in the more specific technical feature of the present invention, the OPP first layer 101 of the bag body 1 is mainly a sheet-like structure, the heat resistant temperature can only reach 125 ° C, and the shrinkage rate after heating is greater than the inner second layer 102 (including There are three layers of PET, AL, and NY) and a third layer of 103. Therefore, in the sealing process, the heat sealing temperature and the production speed must be controlled, so that the inner and outer layers are well matched with each other, so as to avoid improperly adjusting the conveying speed in the production process, and the first layer of the OPP 101 is excessively shrunk by heat, resulting in the inner second layer 102. The aluminum foil is exposed.

Preferably, the bonding adhesive 100 of each layer of the present invention needs to be heat-resistant to 100 ° C or higher, and the heat-resistant adhesive 100 of 100 ° C or higher is used, in order to reduce the OPP of the first layer 101 due to heat shrinkage. Poor appearance, it is also convenient to carry out high temperature and high pressure sterilization technology during packaging. The OPP material of the outermost first layer 101 has a heat preservation effect, so that the content can be prolonged in a high temperature environment when the content is sterilized at a high temperature. Achieve enhanced sterilization.

In addition, in a preferred embodiment, the NY material is added to the second layer 102 of the creation bag body 1 to effectively improve the ductility and toughness of the entire package composition, so that the product packaging is further strengthened to avoid being crushed and crushed. Crack or create a leak. It can completely and effectively improve the traditional bag OPP, PET, CPP after the production of the device seal, it will often destroy the original material structure, resulting in the material is easy to crack and leak.

Thereby, the structure of the creation bag body 1 can conform to the product packaging design, not only can achieve the effect required for the top appearance texture, but according to the carefully developed bag body 1, the thickness of each layer combination material can be determined according to the product content. Subject to different or customary merchandise needs. Moreover, the bonding glue 100 between the layers can also be adjusted according to the process sterilization temperature.

Compared with the prior art, the biggest advantage of the creation bag 1 is that it can reduce the variation of the inner package items when applied, and is most suitable for holding some high-grade health foods, for example, Chinese medicine health liquid 2, etc., but Actually, it is not limited to this, so that it can achieve the practical purpose of preserving the original flavor and locking the essence.

In summary, this creation can indeed achieve the above objectives, comply with the provisions of the Patent Law, and file a patent application. However, the above-mentioned ones are only preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereto; therefore, the simple equivalent changes made by the scope of the patent application and the content of the creation manual are Modifications shall be within the scope of this creation patent.
