Embodiment Construction

[0009] in figure 1 In the middle, set aside the tear (1) and tear line (2).

[0010] in figure 2 In the cross-sectional schematic diagram shown, the food storage space (6) stores food, the space between the isolation layer (8) and the outer packaging layer (10) is reserved for waste (7), the two space sealing positions and the tear line (2) ) Flush to ensure that the two are absolutely separated and open at the same time when they are torn apart along the tear line (2). A sealing tongue (3) that can be turned out freely is set on the inner bottom of the outer packaging layer (10) at one centimeter from the tear line (2). At the end of the sealing tongue (3) opposite to the outer packaging layer (10), add 2 cm Long double-sided tape (4). For example, paper packaging bags need to be coated with edible oil on the inner side (6) of the outer packaging layer (10) and the outer side (5) of the outer packaging layer (9).

Abstract

The invention discloses a multifunctional food packaging bag capable of containing foods and wastes thereof simultaneously. The multifunctional food packaging bag comprises three layers and two completely isolated spaces, namely a food storage space and a waste headspace, wherein sealed positions of the two spaces are leveled to rive-off lines; after the sealed positions are torn along the tearing opening lines, the two spaces are opened simultaneously; a turn-out sealing tongue with a double-face adhesive is arranged at a position, which is lower than the tearing opening line, on the inner side of the waste headspace; and the turn-out sealing tongue is used for sealing the food storage space and the headspace. The multifunctional food packaging bag can effectively package and dispose wastes to prevent scattering of the wastes, is convenient for temporary preservation of foods which are left and can prevent mixed package of the wastes and the foods.

Description

Technical field [0001] The invention relates to an environmentally friendly, hygienic, and convenient food packaging device, which can effectively process food wastes and can conveniently solve the problem of temporary storage of uneaten food after being opened. Background technique [0002] At present, the known food packaging bags have two layers with one space, sealed, sterilized, and reserved tear lines, and do not involve the treatment of food waste. Can not solve the problem of temporary storage of food after opening the bag. The waste is thrown everywhere, destroying public health and polluting the environment. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned shortcomings of current packaging bags and provide an environmentally friendly food bag, which can not only effectively package food, but also package food waste without causing waste to be thrown at will; at the same time, it is convenient when the food is not con...
