Abstract
A polyester suction bubble film used for medicament packing consists of 85-90 percent of PET polyester film and 10-15 percent of bonding agent coated on the surface of the PET polyester film according to weight percent. In the suction bubble film used for medicament packing, the polyester film is main material which does not have binding property, and after the bonding agent is evenly coated on the surface of the polyester film, the suction bubble film is led to have stronger binding property. Compared with PVC, the suction bubble film has stronger property and no toxicity; and compared with cold stamping aluminum composite materials, the property difference of the suction bubble film is not big, while the cost is lowered down much.
Description
Technical field
The present invention relates to a kind of drug packaging with new material and preparation method thereof, be specifically related to that adhesives is uniformly coated on the polyester that forms on the mylar and inhale vacuolar membrane and preparation method thereof.
Background technology
PVC is the abbreviation of polyvinyl chloride film, and because of its price is low, now be widely used in the medicine blister package, but there are a lot of shortcomings in PVC self: barrier property is not strong, and opacity can be poor, and monomer vinyl chloride toxicity is very big, is strong carcinogenic substance.The cold stamping aluminium composite material is the novel medicine blister package material of putting on market in recent years, and barrier property is strong, and is firm with bonding foil, but this cost of product is too high, is not accepted by vast pharmacy corporation.
Summary of the invention
Technical matters to be solved by this invention provides a kind of polyester bubble suction film for packaging medicament, and performance is good, and is nontoxic, and cost is low.
Polyester bubble suction film for packaging medicament of the present invention is characterized in that being made up of the adhesives of PET mylar and its surface coating, and according to the percent by weight meter, the PET mylar is 85～90%, and adhesives is 10～15%.
It is thick that described mylar is generally 0.2-0.4mm, described adhesives adopts the acceptable heat with bonding effect in medical packaging field to melt the type adhesives all can, melt type adhesives (special VC-1) as the heat that Shanghai takes advantage of hawk Industrial Co., Ltd. to produce, solid content is 20%.
In polyester bubble suction film for packaging medicament, the PET mylar is a main material, but itself does not have adhesive bonding property, and adhesives is coated on polyester film surface through uniformly, makes product itself have stronger adhesive power.
The present invention adopts oriented pet film to want material, compares with PVC, and superior performance mainly shows as:
A. the oxygen flow Air permenbility is significantly less than the PVC product;
B. produce monomer vinyl chloride anything but, do not have toxicity;
C. heat sealing strength is higher than the PVC product.
Compare with the cold stamping aluminium composite material, performance is more or less the same, but cost descends a lot.
Test about test method and index with reference to country, its technical target of the product is as follows:
Outward appearance: water white transparency, uniformity do not allow concavo-convex wrinkle, greasy dirt, perforation, impurity
Steam permeable amount: must not cross 2.0g/ (m
2.24h)
Oxygen transit dose: must not cross 25cm
3/ (m
2.24h.0.1Mpa)
The heating expansion and contraction: expansion and contraction answers≤3.0%
Heat sealing strength: must not be lower than 8.0N/15mm.
Description of drawings
Fig. 1 is preparation technology's schematic flow sheet;
Among the figure: 1 unwinding rack 2 is coated with the roller 3 baking ovens 4 chill rolls 5 rolling framves 6 deflector rolls 7 PET mylars 8 glue grooves of arranging net
The specific embodiment
Embodiment 1:
As Fig. 1, commissioning device, the pressure that is coated with the pressure roller of the roller 2 of arranging net is set at 40Mpa, oven temperature is set 50--160 ℃ (can progressively heat up), the PET mylar is pressed to unwinding rack 1, adhesives injects glue groove 8, start equipment operation normal after, with the equipment operation speed setting is in 20--60 rice scope each second, will stir frequently adhesives in process of production, guarantees that adhesives is applied on the mylar uniformly, through being coated with the roller roll-in of arranging net, behind the baking oven hyperthermia drying, carry out rolling, cut, obtain polyester bubble suction film for packaging medicament of the present invention by customer requirement.
Inhale vacuolar membrane, 0.85 ton of PET mylar, 0.15 ton in special VC-1 adhesives by one ton of polyester of every production.
The technical index that the polyester that obtains is inhaled vacuolar membrane is:
Outward appearance: water white transparency, uniformity do not allow concavo-convex wrinkle, greasy dirt, perforation, impurity
Steam permeable amount: 2.0g/ (m
2.24h)
Oxygen transit dose: 25cm
3/ (m
2.24h.0.1Mpa)
Heating expansion and contraction: expansion and contraction 3.0%
Heat sealing strength: 8.0N/15mm.
Embodiment 2:
According to the step of embodiment 1, inhale vacuolar membrane, 0.8 ton of PET mylar, 0.2 ton in special VC-1 adhesives by one ton of polyester of every production.
The technical index that the polyester that obtains is inhaled vacuolar membrane is:
Outward appearance: water white transparency, uniformity do not allow concavo-convex wrinkle, greasy dirt, perforation, impurity
Steam permeable amount: 1.8g/ (m
2.24h)
Oxygen transit dose: 23cm
3/ (m
2.24h.0.1Mpa)
Heating expansion and contraction: expansion and contraction 3.0%
Heat sealing strength: 8.5N/15mm.
