Further, PVDC film layers：For PVDC, because its intermolecular cohesive force is strong, crystallinity is high, in PVDC molecules
Chlorine atom have hydrophobicity, hydrogen bond will not be formed, oxygen molecule and hydrone are difficult to be moved in PVDC molecules, so as to make it have
Excellent oxygen barrier and resistance is moist, and its oxygen barrier is not influenceed by ambient humidity；That is, in any temperature or wet
Under the conditions of degree, have the ability of barrier steam, oxygen, smell and the fragrance of brilliance concurrently, be generally acknowledged comprehensive in terms of barrier
The best plastic package material of energy；Using PVDC gas barrier property, the generation of Food Oxidation denaturalization phenomenon can be delayed, greatly prolonged
Shelf life, while the fragrance of content can be avoided lost and the intrusion of outside bad smell is prevented；It is moist using its resistance,
It can prevent product from occurring dehydration exsiccation, the phenomenon of taste bad, will not prevent quantitative because product absorbs water and damages packaging prototype
Natural wastage (weightlessness) occurs for product.Gas barrier properties do not change with the change of humidity, will not also cause production even if high humidity environment
Product go bad；Using its hypotonicity, loss of aroma can be prevented, and does not absorb remaining smell and off-taste, it is ensured that
The integrality of smell (when packing low fat or high-protein food, this point is particularly important)；Have excellent weather resistance, even if long-term sudden and violent
Outdoor is exposed at, is directly exposed to sunlight, will not also occur packing material and fade and aging phenomenon.
Further, PET film layer：PET is the polymer of milky or preceding yellow highly crystalline, and surface is smooth and has
Gloss；Creep resistance, resistance to fatigue resistance, abrasion-resistant and good stability of the dimension, wear away it is small and hardness is high, with thermoplastic most
Big toughness：Electrical insulation capability is good, is affected by temperature small；Nontoxic, against weather, chemical proof stability are good, and water absorption rate is low,
Weak acid resistant and organic solvent.
PET film layer has advantages below：1. there is good mechanical property, impact strength is 3-5 times of other films, resistance to
Folding endurance is good；2. oil resistant, resistance to fatty, resistance to olefin(e) acid, diluted alkaline, resistance to most of solvents；, can be 3. with excellent high- and low-temperature resistance performance
It is used for a long time in 120 DEG C of temperature ranges, short-period used is resistant to 150 DEG C of high temperature, is resistant to -70 DEG C of low temperature, and to its machine during high and low temperature
Tool performance impact very little；4. gas and vapor permeability are low, existing excellent resistance gas and water, oil and peculiar smell performance；5. transparency
Height, can stop ultraviolet, and glossiness is good；6. nontoxic, tasteless, wholesomeness is good, can be directly used for packaging for foodstuff.
Further, the first CPP film layers and the 2nd CPP film layers：CPP excellent heat resistances, due to PP softening points about
For 140 DEG C, such film can be applied to the fields such as hot filling, retort pouch, aseptic packaging, add acidproof, alkaline-resisting, oil and grease resistance
It is excellent, the preferred material in the fields such as bread product packaging or laminated material is made, itself and food-contact are safe, illustrative
Can be excellent, the local flavor of built-in food is not interfered with, and the resin of different grades may be selected to obtain required characteristic, and also have
Higher flatness, adds the good appearance degree of retort pouch.
A kind of retort pouch of the utility model has advantages below：In use, passing through the first set CPP film layers and second
CPP film layers, add the aqueous vapor and peculiar smell barrier of this retort pouch, and with preferable heat resistance, pass through set PVDC
Film layer so that this retort pouch has preferable gas barrier property and hinders moist, can delay video oxidation deterioration and prevent product from sending out
The phenomenon of raw dehydration change and taste bad occurs, and by set PET film layer, adds the electric insulation of this retort pouch
Property, or even at high temperature, its electrical insulating property is still preferable, creep resistance, fatigue durability, rub resistance and dimensional stability are high,
It is by set frame hot-pressing, edge-sealing line that upper bag sheet and lower bag sheet plastic packaging is integral, facilitate this retort pouch production and
The connection strong degree of upper bag sheet and lower bag sheet in connection, by set sealing strip, adds this retort pouch when in use
Sealing property, when heated, sealing strip is remote due to expanding with heat and contract with cold, its outer wall can with mating groove inwall is even closer fits,
Avoid, because retort pouch causes retort pouch to breathe freely phenomenon after heated due to expanding with heat and contract with cold away from, tearing by set
Breach and folding line structure setting, when opening this retort pouch using this, exert a force at tearing port position and are pullled on the inside of retort pouch,
Tearing port can then extend to folding line direction, so that the purpose for opening this retort pouch is reached, and by set folding line, in side
While open retort pouch, the flatness of the retort pouch for being also sack when opened passes through the first set sealing strip
Button and the second sealing strip, which are buckled, to be equipped with, and can be obstructed the food in retort pouch, it is to avoid food is displaced to tearing port position
Place and make it that food is dropped out when opening retort pouch, and when opening retort pouch and carrying out edible, eaten completely when
After food, it can be buckled by the first sealing strip and the second sealing strip snap fit is closed seal food, it is to avoid food is contacted with extraneous air
The situation of bacteria breed is caused to occur.Its is simple in construction, easy to use, and heat-resisting, acidproof, alkaline-resisting, grease resistance is high, with higher
Barrier steam, oxygen, the ability of smell and fragrance, good stability of the dimension, electrical insulating property be excellent, and production cost is low, environmental protection, whole
Body sealing is high, and applied widely, service life is long, with safe and reliable effect.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
