Description

A new type of outer packaging that can prolong the shelf life of snus in pouches

technical field

The utility model belongs to the technical field of smokeless tobacco products, in particular to a novel outer package capable of prolonging the shelf life of bagged snus.

Background technique

As the most important type of smokeless tobacco products in the world, snus is a wet or semi-moist powder (or shredded tobacco) tobacco product, usually with a moisture content of 20-50%, placed behind the upper lip and gums Between uses, it can be left for 0.5-1 hour. Snus can be further subdivided into bagged snus and snus shredded tobacco in terms of product form. Recently, the market share of bagged snus has grown rapidly. Bagged snus generally uses non-woven fabric as the inner packaging, and plastic or aluminum-plastic as the outer packaging. Since the moisture content of bagged snus is usually high, it needs to be stored under refrigerated conditions, and the shelf life is short, generally no more than three months.

Contents of the invention

In order to solve the technical problem of the short shelf life of the existing bagged snus, the purpose of the utility model is to provide a novel outer package that can prolong the shelf life of the bagged snus.

In order to achieve the above object, the technical scheme that the utility model takes is as follows:

A new type of outer packaging that can extend the shelf life of snus in pouches: it includes two aluminum-plastic/aluminum foil layers of the same shape and size, the two aluminum-plastic/aluminum foil layers are arranged facing each other at the top and bottom, and are sealed and connected around the sides. The inner surface of one of the aluminum-plastic/aluminum foil layers is sealingly connected with a PVC film layer to form a small water bag between the aluminum-plastic/aluminum foil layer and the PVC film layer. The small water bag is filled with water or water and spices, and mixture of emollients.

The PVC film layer can be sealed and connected to any position on the inner surface of the aluminum-plastic/aluminum foil layer, which is convenient to squeeze out the small water bag. It is preferably sealed and connected to the center of the inner surface of the aluminum-plastic/aluminum foil layer.

Further, the sealed connection is preferably heat-pressed or adhesive-sealed.

There are no special requirements for the shape of the two aluminum-plastic/aluminum foil layers and the PVC film layer. The two aluminum-plastic/aluminum foil layers are preferably rectangular, and the preferred PVC film layer is oval; the size of the two aluminum-plastic/aluminum foil layers can be Adjust according to the design requirements of snus products, and the size of the PVC film layer can be adjusted according to the amount of water applied.

The outer packaging of the utility model is made of aluminum-plastic/aluminum foil material, which is sealed by hot pressing or bonding, and inside is a small water bag made of PVC film, which can release water into the aluminum-plastic/aluminum foil bag after being squeezed and broken. When specifically using the new bagged cigar outer packaging product provided by the utility model, firstly, the small water bag made of extruded PVC film, after the small water bag is broken, water or the mixture of water, spices and humectant enters In the snus with non-woven fabric as the inner packaging, the aluminum-plastic/aluminum foil outer packaging can be opened and used for snus products after being balanced for two minutes under the sealed condition of the aluminum-plastic/aluminum foil outer packaging.

Each bag of snus contains 0.2-0.5 grams of tobacco, and the size of the small water bag can be adjusted according to the amount of water applied. If it contains 0.2 grams of tobacco, the moisture content of the bagged snus can be increased from 12% to 30%, and 0.036 grams of water can be put in the small water bag. The sachets can also be filled with fragrances, moisturizers or their mixture with water.

The outer packaging of the utility model can make the bagged snus be processed to about 12% moisture, and the moisture content can be increased during use, without refrigerated storage, and the shelf life can be extended to more than one year. The moisture content of snus in pouches is generally 20-50%. Due to the high moisture content, snus products in pouches need to be stored under refrigeration at 0-4°C, and the shelf life is within three months.

To sum up, the new outer packaging that can prolong the shelf life of bagged snus provided by the utility model can change the moisture content of bagged snus from 20-50% to 12%. Yes, without refrigeration, the shelf life can be extended to more than one year.

Detailed ways

As shown in Figure 1, a new type of outer packaging that can extend the shelf life of snus in pouches: it includes two rectangular aluminum foil layers 1 of the same size, the two aluminum foil layers 1 are arranged facing each other on the upper and lower sides, and are hot-pressed on all sides. Sealed connection, where the center of the inner surface of one aluminum foil layer 1 is heat-pressed and sealed with an oval PVC film layer 2 to form a small water bag between the aluminum foil layer 1 and the PVC film layer 2, and the small water bag is filled with water .

When in use, first squeeze the small water bag made of PVC film 2. After the small water bag is broken, the water enters the snus with non-woven fabric as the inner packaging, and balances for two minutes under the sealing condition of the aluminum foil outer packaging, that is, The aluminum foil package can be opened to use the snus product.
