Description
Technical field
The present invention relates to a kind of food container, more particularly to a kind of film-covered iron food container.
Background technology
With social progress and development in science and technology, the safety in view of food and guarantor are needed to the packaging of food in food service industry
Fresh-keeping function is deposited, original packing box can not meet transport and the shelf appeal of food plus common film, and
And after use, film degradation ability also determine the use that such packing box is increasingly not suitable for modern society on packing box,
Therefore, metal packing material with its good leak tightness, quality is hard, elasticity is good, light blocking is good the features such as, got in food packaging applications
More to occupy critical role.
Traditional canister, application is all had to pass through on the inside of it and is processed, and the material contained by coating process, to people
Body and environment can all produce adverse effect, especially canned food, and traditional processing method is to be entered in the inwall of tank using resin
Row application.But, the harmful substance containing environmental hormone-bisphenol-A class (Bis- in coating used in this coating process
Phenol A) material, it is a kind of internationally recognized environmental hormone, and the problem of be likely to occur dissolution, once dissolution is exceeded, meeting
Harmful effect is produced to human body.
The birth of precoated metal technology, is the revolutionary advancement of metal can production.With its extensive use, conventional metals
Tank production technology and technology are overturned, and the various aspects such as productivity ratio, production cost, sanitation and hygiene, environmental protection are also all advanced
Major step.It, in cold-reduced sheet or plating ferrochrome two sides covering mylar, is that one kind has concurrently that film-covered metal plate such as film-covered iron, which is,
The Metallic Functional Materials of plastic sheeting and sheet metal dual characteristicses, can avoid the metal for dissolving from metallic plate from causing tank
The taste deterioration of interior food or beverage, the generation that local flavor degenerates, content goes bad and perforated.However, existing film-covered iron because
The material of overlay film is to use the general plastic material such as PET, PC, PE or PP film mostly, and its performance is still difficult to meet food
To the requirement of high barrier in packaging, it may occur that because the food taste of improper packing generation dissipates or the problem of food spoilage；And
And film-covered iron container, as canister, its sealing tech is complex, be unfavorable for during packaging for foodstuff quick uses.
The content of the invention
It is an object of the invention to provide a kind of good barrier property, the feature of environmental protection be good, sealing is convenient and good airproof performance film-covered iron
Food container, the problem of solving to propose in background above technology.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of film-covered iron food container, including vessel and the lid with vessel cooperation, described container
Body is the bowl bodies being made up of film-covered iron, and described overlay film iron surface is sequentially provided with the first overlay film, Obstruct membrane and the second overlay film,
Described vessel side wall is provided with some uniform reinforcements, and the bowl mouth end of described vessel is provided with annular edge, institute
The lid stated is connected with annular edge.
Preferably, described the first overlay film and the second overlay film is made up of the raw material of following parts by weight：Polyester (PET) is poly-
40-60 parts of particulate propylene, 4-8 parts of high density polyethylene (HDPE) particle, 10-20 parts of cornstarch, 10-20 parts of acetylation cornstarch,
3-5 parts of PLA, 1-3 parts of lubricant, 0.5-2 parts of oiliness improver, 0.5-1 parts of Tea Polyphenols, 0.5-2 parts of chitosan, tertiary butyl are to benzene
0.1-0.3 parts of 0.5-2 parts of diphenol and chlorinated paraffin；Described Obstruct membrane is made up of the raw material of following parts by weight：PP GRANULES
50-70 parts, 20-40 parts of ethylene-vinyl alcohol copolymer, 10-15 parts of polypropylene maleic anhydride grafts.Cornstarch is mixed into second
Acylated cornstarch is added in overlay film raw material, is remarkably improved the heat sealability of overlay film, while having good degradability again；
The Obstruct membrane set in the middle of two layers of overlay film, can be under conditions of relatively inexpensive, and the raising overlay film barrier of larger amplitude, blocking is covered
Influence of the metal to food taste in film iron.
Preferably, to be that vessel side wall concaves towards the half cone-shaped that vessel is internally formed recessed for described reinforcement
Face, the tapering point of half cone-shaped concave surface is towards the bowl mouth end of vessel, and the round nose of half cone-shaped concave surface is towards vessel
Bowl bottom.
Preferably, described annular edge include in angle connect sealing annular solid and protection edge, sealing annular solid with
The side wall top of vessel is connected and parallel to the bowl bottom of vessel, and the angular range for protecting along and sealing annular solid is
100 degree~140 degree.Smooth sealing annular solid can make lid is be bonded with its to obtain more fine and close sealing, and enhanced package holds
The sealing of device；Protection plays protection lid and sealing annular again along both playing a part of preventing sharp edges from hurting user
The closed edge of body will not be misused the effect ripped.
Preferably, the position that described sealing annular solid is connected with vessel side wall top is provided with chamfering, it is described
Protection is provided with chamfering along top.The chamfering of rounding off can avoid sealing the edge of annular solid and the edge incised wound on protection edge from making
User.
Preferably, the first described overlay film, Obstruct membrane and the successively hot pressing of the second overlay film are in overlay film iron surface, hot pressing temperature
For 150~280 degrees Celsius.Traditional low temperature adhesion technique is that metallic plate and overlay film are combined with each other by binding agent, is bonded
Agent has solvent volatilization in drying, not only not environmentally but also unstable, and heat pressing process can avoid disadvantage mentioned above completely, and with preferable
Compactness and adhesive force.
Preferably, described lid be the first overlay film, PP films or PET film in one kind, lid be hot bonding in
Annular edge surface.The film lid " locked in " operation of hot pressing is convenient, and good leak tightness can substantially reduce the cost of packing container, and not
Burr can be produced, it is safe；Material especially with the first overlay film also has the advantages that degradable, and the feature of environmental protection is good.
Preferably, described lubricant is stearic acid, silicone oil, fatty acid amide, synthetic wax, synthetic fat, stearate
Or one or more mixtures in oleate.
Preferably, described oiliness improver is palmitic acid, oleic acid, laruyl alcohol, cetanol, acid phosphate lauryl or acid
One or more mixtures in phosphoric acid oleoyl ester.
The beneficial effects of the invention are as follows：
The present invention makes food container using the film-covered iron of multilayer coating film, and outer film coating and inner film coating have and can dropped
Solution property and heat sealability is good, intermediate layer overlay film good barrier property, less to the pollution of environment, film-covered iron uses hot laminating technique, does not make
With sticker, so without harmful various chemical substances.The present invention is sealed using laminated film as lid,
Greatly improve sealing and easy to operate, and the visuality of content can be strengthened.
