Abrasion.
5. anti-fog layer is designed as antifoggant being embedded in the structure among cpp film, the method using face coat is avoided, is kept away
The case where having exempted to overflow the antifoggant of face coat because of vegetables respiration discharge large quantity of moisture, improves fresh composite fresh-keeping
The service life of film.
6. traditional vegetables are packed, individual bag being mostly used greatly, is manually weighed, packed, sealing, most fast efficiency is per hour
180 bags.Inefficiency, and hand-filling keeps production cost high, uses this fresh natural complex fresh-keeping film machine, so that it may it is suitable
With packing machine automatic packaging, working efficiency can reach 3600 bags per hour, and working efficiency is totally improved compared with traditional diamond-making technique
20 times.This is modern agriculture, and fresh product processing industry greatly reduces cost of labor.
Description of the drawings
Fig. 1 is fresh natural complex fresh-keeping film sectional view in the preferred embodiment in the utility model.
Specific implementation mode
The utility model is described further below in conjunction with the drawings and specific embodiments.
A kind of fresh natural complex fresh-keeping film suitable for automatic packaging, with reference to figure 1, including anti-fog layer 1, protective layer 2.
Currently, packaging membrane material in the market mainly has cpp film (cast polypropylene film), opp films, (orientation is drawn
Polypropylene stretched film), three kinds of pe films (polyethylene film).Due to opp films (orientation stretching polypropylene film) to temperature compared with
Sensitivity, cpp film (cast polypropylene film) and too crisp not applicable pillow type packing machine are packed automatically, pe films (polyethylene film)
It is too soft, poor transparency, therefore be not suitable for being used alone；So selecting anti-fog layer 1 to be compounded to form composite with protective layer 2 makes
With.
By screening, the combination that may be coextruded has cpp film (cast polypropylene film), and (orientation is drawn with opp films
Polypropylene stretched film) composite material, pet films (high temperature resistance polyester film) and pe films (polyethylene film) composite material,
Pet films (high temperature resistance polyester film) and three kinds of composite materials of cpp film (cast polypropylene film) composite material.Because of pet
Film (high temperature resistance polyester film) and pe films (polyethylene film) composite material clarity are not high enough, and (polyethylene is thin for pe films
Film) anti-fog effect do not highlight not come out, therefore fix cpp film (cast polypropylene film) (orientation stretching polypropylene is thin with opp films
Film) composite material, pet films (high temperature resistance polyester film) and two kinds of cpp film (cast polypropylene film) composite material it is compound
Material is selective.
Again because of the outer layer of pet films (high temperature resistance polyester film) and cpp film (cast polypropylene film) composite material
Pet films (high temperature resistance polyester film) tend to have cut by machine turning, and transport tends to have fold, do not select.Therefore select cpp film
(cast polypropylene film) and opp films (orientation stretching polypropylene film) composite material, with cpp film, (cast polypropylene is thin
Film) it is soft with composite membrane film quality made of opp films (orientation stretching polypropylene film) composite material, high definition is transparent, with pillow formula
Packing machine no-float.
So the anti-fog layer 1 includes cpp film (cast polypropylene film) and antifoggant；The protective layer 2 is specially
Opp films (orientation stretching polypropylene film) layer；The anti-fog layer 1 is coated with polyurethane glue 3 and passes through with protective layer 2 on one side
Dry type is combined in complex to form the fresh natural complex fresh-keeping film.It can avoid with protective layer using the compound method bonding anti-fog layer of dry type
Glue is chemically reacted with antifoggant, generates cloud point, the transparency of fresh natural complex fresh-keeping film is made to decline, and influences product beauty
Degree.
Reduce the formation of water mist in packaging bag by the way that anti-fog layer is arranged, so as to avoid droplets form in packaging bag, protects
Shield vegetables root notch and disconnected leaf are not influenced by water droplet, and reduce vegetable spoilage speed, extend the freshness date of vegetables；It can also be from
Largely, the clarity for increasing packaging bag enables the customer to be intuitive to see article in packaging bag, and it is beautiful to improve product
Degree, more consumer provide facility.
By the way that protective layer is arranged, it ensure that the toughness of fresh natural complex fresh-keeping film, be unlikely to too crisp, be unfavorable for automatic metaplasia
Production.
Due to each have their own feature of various packaging films, opp films (orientation stretching polypropylene film) high definition is soft, antifog skill
Art is most ripe, but very sensitive to temperature, therefore at automatic packaging machine hot-seal, it is easy to happen fold；Cpp film (curtain coating
Polypropylene film) for opp films (orientation stretching polypropylene film), material is clear and melodious, tall and straight, automatic packaging machine sealing
When, notch is beautiful, antifog technology relative maturity, but tends to have cut.Verified, selecting opp films, (orientation stretching polypropylene is thin
Film) it is used as fresh natural complex fresh-keeping film outer layer, i.e., the one side of fresh natural complex fresh-keeping film principle vegetables；(cast polypropylene is thin for cpp film
Film) as fresh composite fresh-keeping film inner layer, that is, fresh natural complex fresh-keeping film close to the one side of vegetables.
Due to the respiration of vegetables, large quantity of moisture can be discharged, contact anti-fog layer for a long time, the anti-fog layer of face coat is anti-
Mist agent can overflow, to influence sensory effects.Method in order to avoid using face coat, the case where causing antifoggant to overflow,
The antifoggant is embedded among cpp film (cast polypropylene film).
In order to avoid because the thickness of fresh natural complex fresh-keeping film is excessive cause packing machine to work when cutter too loudly, abrasion
Packing machine；It is beautiful and in order to avoid causing fresh composite fresh-keeping bag not tall and straight enough because the thickness of fresh natural complex fresh-keeping film is too small
Degree reduces；So between the thickness of the fresh natural complex fresh-keeping film is 2 to 9.
