Abstract
The invention relates to an easily-uncover aluminum plastic compound single film for a glass bottle sealing opening. The film comprises a body, wherein a compound layer, a base layer, and a heat sealing layer are arranged on the body in sequence; a blocking layer is arranged on the compound layer; the body comprises the components in percentage by weight: 29.47%-30.59% of low-density polyethylene, 39.05%-40.81% of linear low-density polyethylene and 29.72-30.36% of an ethylene-(methyl) acrylate copolymer. The film has the advantages that the low-density polyethylene, the linear low-density polyethylene and the ethylene-(methyl) acrylate copolymer are mixed for preparing the body, so that the glass bottle sealing opening is proper in fastness, and is proper in stripping force when being uncovered; a stripping interface is clean, an obvious attenuation phenomenon after refrigeration does not exist, and the film is wide in application range of packaged products; due to arrangement of the blocking layer, the body has the very good blocking performance, stiffness and forming performance, the blocking layer can enable the packaged products to obtain very good protection, the stiffness enables the compound film to be conveniently cut into single pieces, the forming performance enables pressing lines to be processed and arranged conveniently, and the use effect is good.
Description
Technical field
The present invention relates to the sealing of a kind of glass bottle and easily open plastic-aluminum combined monolithic membrane.
Background technology
Just there is glass bottle in China from ancient times, and the past, educational circles thought that vierics were very rare in ancient times, therefore minority ruling class should be only had just may to have and use.But research recently is then thought that ancient glass device is produced and manufactured and is all not difficult, and only not easily preservation event finding later age is rare.Glass bottle is the traditional beverage packaging unit of China, and glass is also the very historied packing of one.When a variety of packing flood the market, glass container is still seized of critical positions in beverage packaging, and to have the irreplaceable packing character of other packing inseparable with it for this.
The principal feature of glass packaging container is: nontoxic, tasteless; Transparent, attractive in appearance, good barrier property, airtight, abundant raw material general, and price is low, and repeatedly can have enough to meet the need use.And there is the advantage of heat-resisting, withstand voltage, resistance to cleaning, both can high temperature sterilization, also can cryopreservation.Just because of it, there is plurality of advantages, therefore become the packing of many beverage first-selections such as beer, fruit tea, Wild Jujube Juice.
Glass bottle manufacturing process mainly comprises: 1, raw material preparative treatment.Block stock (quarz sand, soda ash, limestone, feldspar etc.) is pulverized, makes moist raw material drying, iron-bearing material is carried out deironing process, to ensure glass quality.2, batch preparation.3, found.Glass batch carries out high temperature (1550 ~ 1600 degree) heating in tank furnace or tank furnace, makes it to form even, bubble-free, and meets the liquid glass of forming requirements.4, shaping.Liquid glass is put into the glasswork that required shape made by mould, as flat board, various vessel etc.5, heat treatment.By techniques such as annealing, quenchings, eliminate or produce the stress of inside glass, phase-splitting or crystallization, and change the configuration state of glass.
Glass packaging materials and container have many-sided advantage:
1, glass material has good barrier property, and the gases such as oxygen can well be stoped the invasion and attack of content, the volatile composition of content can be stoped to volatilize in air simultaneously;
2, glass bottle can repeated multiple timesly use, and can reduce packing cost;
3, glass easier can carry out the change of color and diaphaneity;
4, glass bottle safety and sanitation, there are good corrosion resistance and resistance to acid attack ability, are applicable to the packaging of carrying out acidic materials (as fruit-vegetable juice beverage etc.);
5, in addition, because glass bottle is applicable to the production of automatic loading production line, domestic glass bottle auto-filling technology and equipment development is also more ripe, adopts glass bottle packaging fruit-vegetable juice beverage to have certain production advantage at home.
Glass is not crystalline state material, does not have fusing point.It is glassy state organic compound.Deliquescing slowly in the process that temperature raises, usual softening point about 600 degree, temperature is higher, and flowing power can be better.Softening point is the temperature that our the daily glass finished-product seen just has started deliquescing.Fusion cast glass wants the temperature of 1500 degree to be because raw material needs so high-temperature could melt because glass container needs very high temperature to melt, the most employing of the sealing of glass bottle be bottle cap, or add egative film again in bottle cap.If adopt crown cap sealing, need special opener, opening is inconvenient; If adopt vinyl cover sealing, if there is no snap close, do not have antitheft effect.
Above existing market some packaging honey product glass bottle, employing be composite covering film sealing after add spiral cover, spiral cover shields, and composite covering film then plays sealing function, possesses anti-theft feature simultaneously.The liquid diary product product of glass bottle packaging, not yet finds to adopt composite covering film to seal, the composite covering film sealing dairy products glass bottle adopting above honey to pack, when the refrigeration of dairy products product is deposited, can there is the situation of obviously decay, even local shedding, cannot meet refrigeration requirements.
