Abstract
The utility model discloses a kind of printing packaging heat-sealed aluminium foils of heat-resisting type of resistance to boiling, the aluminium foil (1) front surface coated or the aluminium foil ink (2) for being printed with the heat-resisting type of resistance to boiling；The reverse side of aluminium foil is hot sealing layer (3).The ink layer of surface printing coating will not be adhered when the described printing aluminium foil high temperature heat seal；The printing packaging has boiling resistance with heat-sealed aluminium foils simultaneously, and after high temperature and high pressure steam disinfection, ink layer remains unchanged bright-coloured beautiful with the original gloss of aluminium foil.The utility model structure is simple, and function is significant, has the advantage for simplifying coating structure, saving cost, is especially suitable for needing the heat sealed package of the products such as the beverage/food of boiling sterilization.
Description
Technical field
The utility model relates to a kind of heat-sealed aluminium foils, more particularly to a kind of printing packaging of the heat-resisting type of resistance to boiling heat-sealing aluminium
Foil.
Background technique
Aluminium foil has excellent characteristic, such as: light weight, good barrier and processing performance, as packaging material demand
It is big wide.
The packaging of dairy products and beverage/food, it is often necessary to using foil laminated film as sealing heat-sealable material, due to needing
Heat-sealing, these printing aluminium foil surfaces usually need to contact 200 DEG C or so of temperature hot pressing, usual aluminium foil or painting in heat-sealing
The ink of cloth is difficult to be resistant to such high temperature, can frequently result in ink softening and is adhered.On the other hand, aluminium foil ink is due to logical
Be often intolerant to boiling, it is used to directly adopt traditional aluminium foil ink coating and printing, it is difficult to adapt to heat-sealing high temperature and high temperature
The use condition of boiling.To solve both of these problems, traditional method is usually in one layer of resistance to height of printing ink layer surface recombination
The polyester film of warm, resistance to boiling or add apply one layer of resistance to boiling two-component protection gloss oil, to meet wanting for heat-resisting and resistance to boiling
It asks.
Summary of the invention
In view of the drawbacks of the prior art, the utility model provide a kind of packaging for products such as dairy products and beverage/foods,
It is with the resistance to boiling ability of good resistance to heat-sealing, do not need the overlay film on printing surface or add the printing for applying the two-component gloss oil of resistance to boiling
It is packed for heat-sealed aluminium foils.
The technical solution adopted in the utility model is a kind of printing packaging heat-sealed aluminium foils of the heat-resisting type of resistance to boiling, described
Aluminium foil (1) front surface coated or be printed with the aluminium foil ink (2) of the heat-resisting type of resistance to boiling；The reverse side of aluminium foil is hot sealing layer (3).
Preferably, the aluminium foil ink of the heat-resisting type of resistance to boiling, resin system are that heat cured epoxy is modified poly-
Ester resin system, comprising: colorless and transparent gloss oil and other various colorss.
Preferably, the aluminium foil ink of the heat-resisting type of resistance to boiling is gravure type liquid ink, viscosity
(Zan 4#/ 25 DEG C) are as follows: 10 ~ 60 ", solid content: 35 ± 15%(150 DEG C/30 minutes) and, heat resistance: 220 DEG C/15 seconds；Resistance to steaming
Boiling property: 121 DEG C/45 minutes.
Preferably, the hot sealing layer is thermoplastic liquid heat-sealing glue layer or PE overlay film hot sealing layer or CPP overlay film hot sealing layer
One of.
Preferably, the printing packaging heat-sealed aluminium foils of the heat-resisting type of resistance to boiling of one kind, suitable hot sealing process are as follows: heat
180 ~ 220 DEG C of temperature of envelope seals pressure: 2 ~ 5kg/cm2 , the heat-sealing time: 1 ~ 5 second；Heat seal strength are as follows: (180 ° of 5 ~ 12N/15mm
Removing).
The beneficial effects of the utility model are: surface printing painting will not be adhered when the described printing heat-sealed aluminium foils high temperature heat seal
The ink layer of cloth；The printing packaging has boiling resistance with aluminium foil simultaneously, and after high temperature and high pressure steam disinfection, ink layer is still fresh
It is gorgeous beautiful with the original gloss of aluminium foil.The utility model structure is simple, and function is significant, have simplify coating structure, save at
This advantage, has reached the function of previous multilayered structure, is especially suitable for the heat-sealing of the heat-sealing type aluminum foil sealing film of resistance to boiling and food
The fields such as packaging.
Detailed description of the invention
Fig. 1 is a kind of sectional view of the printing packaging heat-sealed aluminium foils of heat-resisting type of resistance to boiling.
Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing 1 to technical solutions of the utility model.
Referring to Fig.1, the utility model provides a kind of printing packaging heat-sealed aluminium foils of heat-resisting type of resistance to boiling, the aluminium
Foil (1) front surface coated or the aluminium foil ink (2) for being printed with the heat-resisting type of resistance to boiling；The reverse side of aluminium foil is hot sealing layer (3).
The selection of the aluminium foil (1) with a thickness of 0. 005-0.009mm printing packaging aluminium foil.
The aluminium foil ink (2) of the heat-resisting type of resistance to boiling in the present embodiment, selects the resistance to resistance to steaming of heat-sealing of SWH-AL series
Boil serial aluminium foil coating ink (production of Shanghai Wan Han Industrial Co., Ltd.).
Coating and printing technique are as follows: coating machine, five sections of warm area settings are printed with five sections of drying tunnels using scraper anilox roll are as follows:
90 DEG C ~ 120 DEG C ~ 150 DEG C ~ 180 DEG C ~ 100 DEG C, printing coating speed is 50 ~ 90 meters/min.
It is coated with the aluminium foil reverse side of ink in the above printing, using gravure coater, coating thermoplastic liquid heat-seal adhesive
Layer, the present embodiment use H25 heat-sealing adhesive (production of Shanghai Wan Han Industrial Co., Ltd.), and coating dry measure is 5 ~ 10g/m2。
The said goods wind detection after drying tunnel is dry, it can obtain the utility model product.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Based on this technology essence
And that makees modifies or replaces, the model for various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses, should all cover in the claim of the utility model and the range of specification.
