Vacuum packaging bag internally provided with wet type mask and forming method of vacuum packaging bag

Abstract

The invention provides a vacuum packaging bag internally provided with a wet type mask and a forming method of the vacuum packaging bag. The vacuum packaging bag comprises the mask, at least one kindof essence for the mask and a rectangular outer packaging bag. The essence is adsorbed on the mask. The rectangular outer packaging bag is provided with a to-be-sealed side on the upper portion. Afterthe mask is put into the rectangular outer packaging bag from an opening of the to-be-sealed side on the upper portion, the rectangular outer packaging bag is filled with the essence for the mask through the opening, then a vacuum operation machine table is used for vacuum operation, the interior of the rectangular outer packaging bag is in a vacuum state, meanwhile, the to-be-sealed edge is subjected to hot-press sealing operation, a completely-sealed sealed side is formed, and therefore the vacuum packaging bag internally provided with the wet type mask is obtained; and the oxidization timeof active ingredients in the essence for the mask is prolonged, the storage expiry date of the mask is prolonged, and volume production of the vacuum packaging bag is facilitated.

Description

technical field [0001] The invention relates to a vacuum packaging bag with a built-in wet mask and its forming method, especially a vacuum packaging bag with a built-in wet mask, so as to slow down the oxidation time of the active ingredients in the essence of the mask and increase the storage efficiency of the mask. period, and is conducive to mass production. Background technique [0002] There are many relevant existing mask packaging bag methods in the field of facial mask packaging bags, such as the Chinese Taiwan invention patent I405547, but the above-mentioned background technology still needs improvement. When an existing facial mask packaging bag is filled with a facial mask with essence (or dressing), it is sealed to complete a packaging bag with a built-in wet facial mask. An appropriate amount of preservatives or antibacterial agents are added to the essence to avoid mildew on the wet mask due to long-term storage when the packaging bag is opened at the consum...

AI Technical Summary

Problems solved by technology

When an existing facial mask packaging bag is filled with a facial mask with essence (or dressing), it is sealed to complete a packaging bag with a built-in wet facial mask. An appropriate amount of preservatives or antibacterial agents are added to the essence to avoid mildew on the wet mask due to long-term storage when the packaging bag is opened at the consumer end. Both drugs are not good for human skin, and must be marked on the packaging bag, which relatively affects the purchase willingness of consumers who value safety, and is also not conducive to sales at the manufacturing end.

[0003] After putting the mask with essence in a packaging bag, if the vacuum operation can be used to remove the air in the packaging bag before sealing, it can effectively slow down the oxidation time of the active ingredients in the essence of the mask To prevent mildew, and then increase the shelf life of the mask; however, no manufacturing end has yet applied the vacuum operation method to the packaging method of the vacuum packaging bag with a built-in wet mask, and there is no vacuum packaging bag for a built-in wet mask on the market However, a special vacuum operation machine is designed. Therefore, if the current vacuum operation method is to be applied to the vacuum packaging bag with a built-in wet mask, it can only be carried out by means of a general food or industrial vacuum operation machine. The operation method is not specially designed for the vacuum packaging bag with built-in wet mask. For example, for the whole face wet mask or the folded wet mask, its shape (mask thickness) is generally flatter than the food, so the existing vacuum operation machine , especially the airtight chamber used for vacuum operation is relatively large, which is not conducive to the vacuum operation of the vacuum packaging bag with built-in wet mask (that is, to increase the vacuum operation time), and is relatively unfavorable for the mass production of vacuum packaging bags with built-in wet mask
