Mixing Ratio :
Its recommended that the mixing ratio and mixed adhesive be diluted with ethyl acetate or acetone and MEK with the minimum water content of 0.1% to a solid content as such as:
- Especially provides for lamination PET to PAPER is mixing ratio 100 parts by weight of GP-50 to 15 parts by weight of GP-50H with solid content of 25-35%.
- For General Lamination of OPP//PET, PET//LLDPE, PET//Alu//CPP, etc. That the mixing ratio should 100 parts by weight of GP-50 to 15 parts by weight of GP-50H with a solid content of 30-40%.
APPLICATION AREAS :
HILAM GP-50 + GP-50H is recommended for laminating substrates for flexible packaging for Soap wrappers, snack foods, bread, coffee, chocolate, milk, meat, cheese and non aggressive dry products packaging, etc. Laminate substrates used are BOPP, PET, METALIZED FILM, CPP, LLDPE, ALLUMINIUM FOIL, PAPER, etc.
APPLICATION GUIDE :
- Coating Method :
HILAM adhesive is applied on all dry laminating machines with gravure roll coating or cylinder coating. - Drying Temperature :
With Dry chamber temperature or drying web temperature of 65°C and combining with Nip roll temperature of 65°C -95°C are recommended to completely remove the solvent carrier.
Ensure complete removal of solvent. To prevent retention, drying condition has to be adjusting to substrate, application weight and machine speed.
High Laminating temperatures together with high line pressure of calendar improve the bond strength and optimal appearance of laminated properties. - Coating Weight /Deposit Weight :
For normal applications the dry adhesive coating weight may range from 2 – 2.8gsm, depending on the film or foil combination and the end use of the laminates. However for the specific application like in thicker / porous substrate (such as paper and board), higher coating weight from 3.0 to 3.5gsm of dry adhesive recommended.
If the coating weight of the adhesive which is coated on films is too small, than the appearance will be not clear and will look like bubble, coating, roll mark, the bond strength will not enough either; and just the opposite if the coating weight is too-much, than the appearance of the film will be blur and will look like tunneling, wrinkle, shrinkage and etc. - Speed Line :
Fastest line speed 60-150 m/min. - Aging Time :
48 hours at approx 50°C – 60°C at aging room. - Curing Time :
The laminate can be process rewound and slit after 1-2 days for triplex laminates is possible 24 hours after duplex production. Good lamination bond are achieved within 7-12 days after lamination of storage at room temperature. - Use Recommendation :
The bonding strength makes a difference according to each film, even the sources materials of film are same, but their bonding strength can be quite different and beside additives and slip agents on polyethylene and polypropylene film, aggressive ingredients, printing inks, corona treatment and film coating are of significant importance for the final performance properties.
All the polyolefin films must be treated prior to lamination and treated surface to used lamination. The recommended treatment level is 38 ~ 40 dynes per centimeter to achieve minimum required surface wet ability level.
Since the ingredients in films and inks may interfere with the good performance of this adhesive, customers are strongly recommended to carefully test GP-50 + GP-50H before using it in production, to check its suitability for each and every end use requirement. - Pot Life :
The pot life of mixed adhesive is 12-24 hours depending on the temperature and the quantity of the mixture. - Cleaning :
The application system of the equipment should be cleaned with solvent after every operation. Special care should be taken to avoid adhesives drying and curing in the cells of the gravure application cylinder. - Storage /Caution & Safety :
The adhesive and hardener must not be stored in direct sunlight or flame or spark source and stored in the place where cool, dry and well ventilated and keep stored in the original unopened and undamaged container. Opened containers of the material have to be closed immediately and the material should be consumed within a short period. Avoid contact with skin & eyes. Safety regulations with regard to handling of materials as well as material safety data sheets have to be followed. - Standard Packing :
HILAM GP-50 is available in 200 Kgs/Barrel or 50 Kgs/Barrel and GP-50H in 24 Kgs/Pail or 6 Kgs/Can.
