Water Vapor Transmission Rate at 23 ℃
Test-lab: SKC (Korea) research with Fraunhofer (Germany) R&D

Importance (needs) of developing technology

This technology is related to manufacturing technology of new film with good barrier gas and organic substance.

barrier film is actively adopted to packaging in food/ beverage/ medical products/ and industrial parts. In particular, high barrier effect on leak of gas, smell and vapor in substitution packaging and beverage packaging or vacuum packaging, preventing from microorganism growth, content oxidation, and fragrance & solvent.

However, the pre-existing products are manufactured by accumulating various polymers, which has made it thicker and complicated process and bad gas barrier effect.

Besides, polymer barrier film from molecule level and some materials have been not appropriate to manufacture food & beverage packaging, or not approved by authorities. To overcome such weakness requires new manufacturing method of film with very excellent barrier effect at lower prices.

Development of packaging film with good barrier effect, is expected to make great ripple effect on the related areas such as food & logistics, by increasing the food storage.

Barrier Coatings: Summary of Coating Technologies

Marketability - characteristics of consumer needs

Consumers'needs

Needs of characteristics of the pre-existing barrier
  OTR < 1cc/m2 / Day (PET-RHB-10% expensive PET),
  WVTR<1 g/m2 /Day (PET-RHB-10)
Excellent Adhesion layer
  Adhesion layer effect increased, after plasma treatment.
Excellent vacuum packaging characteristics
  Whether automatic vacuum packaging is enabled

MULTI-Layer laminating

Separate facilities required for treatment fo PE/PP Laminating and FINISH SURFACE

PSII technology without deformation of Adhesion layer

PSII (Plasma Source Ion Implantation)

No materials deformation due to low temp. process
Very high strength of Adhesion layer due to formed ion injection layers (Hair Crack minimized)
No oxidation or damage on surface
Adjustable depth of surface less than micron
  

PSII method applied Barrier Film making

Applicable area- chemicals save (Amino acid save film)

Needs

Currently used bottle-type save container applied
To increase usability and long-term storage, first changed to vinyl packaging
Changed to bottle type again, due to dioxin detected in vinyl packaging

Solution

Fundamental removal of dioxin detect
Great decrease in oxygen transmission rate & moisture transmission rate
Barrier Film is changed to multi layers (Adhesion layer technology required)

If this item developed and completed, applicable items are as follows:

Food packaging
Meat & dairy products packaging
Medical products packaging
Industrial products packaging
