Problems solved by technology

However, because most of the existing film-coated iron materials are made of general-purpose plastic materials such as PET, PC, PE or PP film, its performance is still difficult to meet the requirements for high barrier properties in food packaging, and it may occur due to poor packaging. The resulting food taste dissipates or food deteriorates; and the film-coated iron container is used as a metal container, and its sealing technology is relatively complicated, which is not conducive to the rapid use in the food packaging process

Embodiment 1

[0044] Such as figure 1 with figure 2 The illustrated food packaging container with film-coated iron includes a container body 1 and a cover 2 matched with the container body. The container body is a bowl-shaped body made of film-coated iron. The reinforcing rib 3 is a semi-conical concave surface formed by the side wall of the container body concave to the inside of the container body, the tapered end 31 of the semi-conical concave surface faces the bowl end of the container body, and the round end 32 of the semi-conical concave surface Towards the bottom of the bowl of the container body. The bowl mouth end of the container body is provided with an annular edge 4, and the cover body is connected with the annular edge. The ring edge includes a sealing ring body 41 and a protective rim 42 connected at an angle. The sealing ring body is connected to the top of the side wall of the container body and parallel to the bottom end of the bowl of the container body. The angle between...

Embodiment 2

[0051] Same as Example 1, the difference is that the first covering film and the second covering film are made of the following parts by weight: 50 parts of polypropylene particles, 8 parts of high-density polyethylene particles, 16 parts of corn starch, acetylated 16 parts of corn starch, 4 parts of polylactic acid, 1 part of synthetic fat, 0.5 part of oleic acid, 1 part of tea polyphenols, 1.5 parts of chitosan, 1.7 parts of tert-butyl hydroquinone and 0.3 parts of chlorinated paraffin. The barrier film is made of the following raw materials in parts by weight: 60 parts of polypropylene particles, 30 parts of ethylene-vinyl alcohol copolymer, and 10 parts of polypropylene maleic anhydride graft. The cover body is a PP film, and the cover body is hot-pressed and bonded to the surface of the ring edge.

[0052] The film-coated iron food packaging container prepared in this example was made into test specimens for adhesion and corrosion resistance testing. The test results were: a...

[0054] Same as Example 1, the difference is that the first covering film and the second covering film are made of the following parts by weight: 50 parts of polyester (PET) particles, 8 parts of high-density polyethylene particles, and 16 parts of corn starch , 16 parts of acetylated corn starch, 4 parts of polylactic acid, 1 part of synthetic wax, 0.5 parts of oleic acid, 1 part of tea polyphenols, 1.5 parts of chitosan, 1.7 parts of tert-butyl hydroquinone and 0.3 parts of chlorinated paraffin . The barrier film is made of the following raw materials in parts by weight: 60 parts of polypropylene particles, 30 parts of ethylene-vinyl alcohol copolymer, and 10 parts of polypropylene maleic anhydride graft.

[0055] The film-coated iron food packaging container prepared in this example was made into test specimens for adhesion and corrosion resistance testing. The test results were: adhesion level 1 and corrosion resistance level 0.

Abstract

The invention provides a laminated steel food container with good barrier property, excellent environmental friendliness, sealing convenience and good leaktightness. The laminated steel food container comprises a container body and a cover body matched with the container body, wherein the container body is a bowl-shaped body made of laminated steel; a first membrane, a barrier membrane and a second membrane are sequentially arranged on the surface of the laminated steel; a plurality of uniformly distributed reinforcing ribs are arranged on the side wall of the container body; an annular edge is arranged at the bowl rim end of the container body; and the cover body is connected with the annular edge. The food container is made of the laminated steel adopting multiple layers of membranes, the outer-layer membrane and the inner-layer membrane are degradable and good in heat sealability, the intermediate-layer membrane has good barrier property, environmental pollution is less, the laminated steel adopts a heat compounding process, no adhesives is used, and accordingly, various chemical substances harmful to a human body are not contained. As the cover body is made of a composite film to perform sealing, the leaktightness is greatly improved, the operation is convenient, and the visibility of a content can be enhanced.

Description

Technical field [0001] The invention relates to a food packaging container, in particular to a film-coated iron food packaging container. Background technique [0002] With social progress and technological development, food packaging in the food industry needs to take into account food safety and preservation functions. The original packaging box plus ordinary film can no longer meet the requirements of food transportation and storage, and it is in use Later, the degradability of the film on the packaging box also determines that this type of packaging box is less and less suitable for use in modern society. Therefore, metal packaging materials are characterized by good airtightness, hard texture, good elasticity, and good light blocking properties. The field of food packaging is becoming more and more important. [0003] Traditional metal containers must be painted on the inside, and the substances contained in the coating method will have harmful effects on the human body and t...
