Abstract
The utility model relates to a kind of gluing Du Pont spies to defend strong heat sealed package easily tore film, belong to medical device package auxiliary material, consist of: the Du Pont spy as substrate defends strong synthesis body paper (1), the substrate is divided into two surfaces of obverse and reverse, the front is printing surface, can print the mark of packed article；The reverse side is coated face, and composition is: being coated with one layer of water base light release primary coat glue (2) first, one layer of powerful water-base heat-seal adhesive (3) is then coated on primary coat glue.The water base heat-seal adhesive coated face and plastic film (such as: PETG, PE, PVC) have a suitable heat seal strength when sealing, pulling force is moderate when unlatching, be easily peeled off and be open it is clean complete, with good gas permeability.Due to solving the Environmental Safety and dissolvent residual risk of solid thermal melten gel and solvent-based thermal melt layer using water-base cement, but also the gas permeability of such heat sealed package easily tore film is more preferable, it is the upgraded product of the similar packaging easily tore film of tradition.
Description
Technical field
The utility model relates to a kind of gluing Du Pont spies to defend strong heat sealed package easily tore film, the heat-sealing packet for medical instrument
Dress, belongs to medical device package Material Field.
Background technique
Spy defends the trade mark that strong (Tyvek. Du Pont cloth) is a series of articles of sheet material of E.I.Du Pont Company, it is by countless tiny poly-
Spunbonded type alkene made of vinyl fiber is spunbond (Spunbonded Olefin), this unique spray spinning technique can produce weight
Amount is light, is unlikely to deform, flexible smooth, light and handy tough and tensile, splendid opacity, moisture proof, water resistant stain, is that a kind of purposes is extremely wide
General material.
Spy defends heat-flash seal packaging film, since it has the advantages that protrusion, obtains in medical device package field more and more
Application, such as: Medical special defends strong lid material, the more blister packaging for more high-end some third class medical instruments,
It is used as hard plastic uptake sealing lid material, and some plastics, such as: PETG, PVC, PS, PP, PET vacuum formed box material heat sealing.
However, the gluing spy currently used for medical device package field defends strong material, and substantially external import, state-owned enterprise of state
Industry is rare can be self-produced.It is difficult to grasp this is because gluing spy defends strong heat sealability, and the gluing spy of import defends strong used
Glue also has coating glue based on solid thermal melten gel, but glue-spread is generally very big, reaches 11-20g/m2Or more, heat-sealing
Intensity is often very big, and even up to 7N/15mm or more, causes to be not easily stripped sometimes.
Utility model content
In view of the deficienciess of the prior art, this case, which provides a kind of gluing Du Pont spy, defends strong heat sealed package easily tore film, adopt
It is finished the aqueous heat-seal adhesive coating of loopful guarantor, solves the security hidden troubles such as environmental pollution and dissolvent residual, but also gluing
Dialyzing paper has better gas permeability, while having suitable peeling force, removing that can be clean, so that every comprehensive
It can be further improved.
To achieve the above object, this case is achieved through the following technical solutions:
A kind of gluing Du Pont spy defends strong heat sealed package easily tore film, structure composition are as follows: the Du Pont spy as substrate defends strong synthesis
Body paper, the substrate are divided into two surfaces of obverse and reverse, and the front is printing surface, can print the various marks of packed article
Show；The reverse side is coated face, is the adhesive layer of heat sealed package, and composition is: being coated with one layer of water base light release primary coat first
Then glue is coated one layer of powerful water-base heat-seal adhesive on primary coat glue.
Preferably, the gluing dry measure of the water base light release primary coat glue is 3.0 ~ 5.0g/m2, defended with substrate Du Pont spy
Strong heat seal strength are as follows: 2.5 ~ 4.5N/15mm.
Preferably, the gluing dry measure of the powerful water-base heat-seal adhesive is 3.0 ~ 5.0g/m2And the combination of primary coat glue is strong
Degree is greater than 4.5N/15mm.
Preferably, the powerful water-base heat-seal adhesive and plastic foil heat-seal bond fastness are greater than 5.0N/15mm.
Preferably, after the easily tore film and plastic basis material heat-sealing, when removing, splitting be Du Pont spy defend strong surface and
Removing between water base light release primary coat glue interface, the whole peel strength between easily tore film and plastics are as follows: 2.5 ~ 4.5N/
15mm。
Compared with traditional gluing Du Pont spy defends heat-flash seal packaging film, the beneficial effects of the utility model are: this case uses
It is double to apply different types of aqueous heat-seal adhesive, so that whole heat-sealing peel strength is controllable, to be easily peeled off；Due to this case material
Spread is less compared with the spread of such product currently on the market, because having better gas permeability, is convenient for ethylene oxide
Disinfecting action.Heavy environmental pollution existing for solid thermal melten gel and solvent-based thermal adhesive layer, safety in production, molten is also overcomed simultaneously
The remaining risk hidden danger of agent；When gluing spy defends heat-flash seal packaging film and plastics and seals, due to glue-line specific flexibility and
Suitable heat seal strength, is easily peeled off, and when unlatching is open flat and smooth, has good comprehensive performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that a kind of gluing Du Pont spy defends strong heat sealed package easily tore film.
Specific embodiment
The following describes the utility model in further detail with reference to the accompanying drawings.
As shown in Figure 1, a kind of gluing Du Pont spy of this case defends strong heat sealed package easily tore film, structure composition are as follows: as substrate
Du Pont spy defends strong synthesis body paper 1, which is divided into two surfaces of obverse and reverse, and the front is printing surface, can print quilt
The various marks of packing material；The reverse side is coated face, is the adhesive layer of heat sealed package, and composition is: being coated with one layer first
Water base light release primary coat glue 2, is then coated one layer of powerful water-base heat-seal adhesive 3 on primary coat glue.
In the present embodiment, water base light release primary coat glue selects the medical aqueous heat-seal adhesive of ulida 300 (ulida is
