Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the following examples, but the scope of the present invention is not limited to the following specific examples.

Unless otherwise defined, all terms of art used hereinafter have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the present invention.

Unless otherwise specifically stated, various raw materials, reagents, instruments, equipment and the like used in the present invention are commercially available or can be prepared by an existing method.

Example 1

As shown in fig. 3a, 3b and 4 to 8, the embodiment provides a liquid leaking bowl cover 2, wherein a first lifting piece 24 and a second lifting piece 25 extending outwards are arranged at the edge of the bowl cover 2, the first lifting piece 24 and the second lifting piece 25 are symmetrically distributed at two sides of the liquid leaking bowl cover 2, and specifically, the first lifting piece 24 and the second lifting piece 25 are distributed on the symmetry axis or diagonal line of the bowl cover 2. The bowl cover 2 sequentially comprises a first stripping layer 21, an adhesive layer 22 and a second stripping layer 23 from top to bottom; the first peeling layer 21 includes: a protective layer 214, a printing image and text 213, a barrier coating 212 and a starch film layer 211; the second stripping layer is provided with a plurality of liquid leakage openings 26, the liquid leakage openings 26 are formed by linear type transverse cuts 261 penetrating through the second stripping layer 23, and the openings of the transverse cuts are provided with protrusions 262; the adhesive layer 22 consists of a first adhesive layer 221 and a second adhesive layer 222, wherein the coating area of the first adhesive layer 221 is a first uncovering piece 24, the annular area of the edge of the bowl cover is a half of the area of the annular area, and the coating area of one side of the annular area, which is close to a second uncovering piece 25, is a transverse cut 261 and a protruding part 262; the second adhesive layer is coated on the other area.

In this embodiment, the first release layer is prepared by a surface printing process or an inner printing process, the barrier coating 212 is coated and bonded on the surface of the paper base or the film base in a coating manner, the protective layer 214 and the printed image and text 213 are transferred to the surface of the paper base or the film base by the printing process, and no additional adhesive is required between layers. Specifically, as shown in fig. 3a, a surface printing process is adopted on a starch film 211 which is easily naturally degraded, a barrier coating 212 is coated on the upper surface of the starch film 211, the barrier coating 212 is also a modified microfibrillated cellulose aerogel, the surface strength of the starch film 211 is enhanced, and simultaneously the oxygen and gas barrier properties of the starch film 211 are improved, then a printing pattern 213 is printed on the barrier coating 212 and a protective layer 214 is coated, so as to enhance the wear resistance and the service cycle of the printing pattern 213, thereby obtaining a first peeling layer 21, an adhesive layer 22 is coated on the lower surface of the first peeling layer 21, and the adhesive layer 22 and a second peeling layer 23 are adhered together to form a main body film material of the liquid-leaking bowl cover.

As shown in fig. 3b, the first peeling layer 21 is formed by a back printing process, an adhesive layer 22 is coated on the lower surface of the first peeling layer 21, and the adhesive layer 22 and the second peeling layer 23 are bonded together to form a main film material of the liquid-leaking bowl cover, which has the same functionality as the main film material of the liquid-leaking bowl cover shown in fig. 3 a.

The adhesive layer in this embodiment can adopt commercially available glue to prepare and form, can adjust the peel force on adhesive layer through the glue that adopts different sticknesses, and wherein the peel force on adhesive layer one is 5~7N 15mm, and the peel force on adhesive layer two is 1~3N 15mm, and the peel force on adhesive layer one 221 is greater than the peel force on adhesive layer two 222, forms adhesive layer 22 jointly, again with second peel ply 23, aluminium foil layer promptly, closely bonds together. The first adhesive layer 221 has strong peeling performance, so that the first peeling layer 21 and the second peeling layer 23 can be peeled off only by achieving destructive peeling force in the area coated with the first adhesive layer, and the area coated with the second adhesive layer 222 only has weak peeling performance, so that the first peeling layer 21 and the second peeling layer 23 can be completely peeled off only by needing smaller peeling force in the area coated with the second adhesive layer, for example, the two peeling layers can be completely peeled off by using both hands, so that the simple, fast and convenient separation and recycling of aluminum and plastic are realized, a consumer can separate the aluminum and plastic layers after using the aluminum and plastic layers, the increase of the recycling cost caused by recycling methods such as a mechanical method and a chemical method in the existing aluminum and plastic recycling process is avoided, and particularly, if the chemical separation method is improperly treated, much sewage is discharged, and is unfavorable to the environment and even unavailable.

As shown in fig. 4, the bowl cover 2 having the first peeling layer 21, the adhesive layer 22 and the second peeling layer 23 is through-die cut according to the designed shape and size of the bowl cover 2 to form the bowl cover 2 having the first peeling sheet 24 and the second peeling sheet 25, and through-die cuts are formed in the second peeling layer 23, i.e., the aluminum foil layer, through cross cuts close to the second peeling sheet 25, while no die cuts are formed in the area of the first peeling layer 21, so that the bowl cover 2 still has good sealability and barrier property under the condition of the first adhesive layer 221 having strong adhesiveness.

As shown in fig. 5 to 8, when the first peeling layer 21 at the second peeling layer 25 is peeled off by a large external force, such as a force applied by two hands, the transverse cut 261 penetrates through the second peeling layer 23, i.e., the aluminum foil layer, so that the transverse cut is separated vertically, the second peeling layer 23 facing the first peeling layer 24 of the transverse cut 261 is pulled upward together with the first peeling layer 21 under the action of the first highly adhesive layer 221, the second peeling layer 23 facing the second peeling layer 25 of the transverse cut 261 is separated from the first peeling layer 21, and when the first peeling layer 21 and the second peeling layer 23 are separated to the protruding portion 262 on the transverse cut, the first peeling layer 21 and the second peeling layer 23 are difficult to be peeled off continuously and stopped under the action of the first adhesive layer 221, so that the liquid leakage port 26 is formed in the transverse cut. In the embodiment, the size and the shape of the transverse cut are not strictly limited, so that soup can be conveniently filtered out, and noodles and foodstuff can be isolated.

Example 2

As shown in FIGS. 1-2, the present embodiment provides an environment-friendly and easily-recycled instant noodle packaging bowl 1, which comprises a bowl body 12 and a bowl bottom 13: a flange 11 is arranged at the opening of the bowl body, the bowl opening flange 11 is connected and combined with the upper part of the bowl body 12, and the connecting and combining part is in an arc shape; the outer side of the bowl body 12, which is not in contact with food, is provided with a printing image-text 103 and a protective layer 104, the protective layer 104 covers the printing image-text 103, and the inner side of the bowl body 12, which is in contact with food, is provided with a barrier coating 102, so that the functions of oil resistance, water resistance, oxygen resistance and temperature resistance are realized.
