Polyurethane Adhesive for Food Package
JYE2075A/B is a common two-component ethyl soluble polyurethane adhesive designed for general structure.
This product is suitable for the lamination among PE, PP, PET and PA. It has good performance of lamination.
1. Lamination film has the features of good initial adhesion, high transparency, high peeling strength, etc.
2. It has a good performance of wetting to the film, and it’s especially good at coating process.
3. It conforms to the Food Hygiene Law of the P.R.C.
4. It conforms to the Adhesive regulations for food packaging of China National Adhesives Industry Association.

Attention: The moisture of EAC, no more than 300ppm, is the most suitable solvent for dry lamination. In addition, MEK, TO,
ACETONE etc., whose moisture is no more than 300ppm, also can be used as solvent. It will reduce The effective content of
hardener when there is active hydrogen, such as alcohol, amine, in the solvent.
Standard Mixing Ratio(weight): JYE2075A:JYE2075B=20:4
Dilution: Pour the EAC into the JYE2075A, and mix absolutely. Add JYE2075B before mix entirely.
Coating: The dry basis coating use can be 2.0-3.5g/m2 in order to math the requirement of use purpose, materials
and composition. Lamination film, which need hot working or heavily process, should use more adhesive. On the
contrary, the use should be less. In addition, the printing film should use more adhesive, too.

Normal concentration is 25~40%. The most benefit use concentration of roller coating is around 35%.
For the volatilization of solvent on the film, please equip the dry machine with strong wind, high speed and
applicable temperature. If the dry system consists of three parts, the temperature should be 50~60℃, 60~70℃
and 70~80℃ from the entrance to the exit in the order.
Lamination Temperature
50~80℃ is usual. The temperature should be controlled at 50~60℃ if the film is easy affect by the temperature.
Lamination Pressure
At the premise of protecting the film from damage, increase the pressure as high as possible.
Carry on the cutting process of lamination product at 50±5℃, 24 hours after curing. Extend curing time if there is
a process of making bags. The curing needs over 7-10 days when curing in the barn over 20℃.
JYE2075A is 20kg/drum, JYE2075B is 4kg/drum.
This product should be stored in a cool and dry place. The validity period of JYE2075A is 12 months, and the
JYE2075B is 10 months.
1. Have a corona treatment to the film of Polyethylene and Polypropylene is necessary. The surface tension
should be more than 52mN/m as large as possible, and the surface tension of PET should be no less than
2. Environment humidity and moisture in the diluent make an obvious effect on lamination effect. Increase the
use of JYE2075B when in the High temperature and high humidity season.
3. Remaining adhesive: Do not use remaining adhesive in principle. If there are too much adhesive remained.
Saved tightly away from heat and ignition sources after dilution. The remaining adhesive can be used as
diluent, which should poured into the new prepared adhesive slowly and can not be used at aluminum foil
lamination. Do not use the remaining adhesive if there is the emergence of opaque, translucent or thickening
4. It should be selected before use. The type and concentration of additive make an effect on the strength of
5. Do not use this product with other adhesive.
6. Keep tightly in the shadow with the attention of fire and eliminating static electricity.
