New product recommendation Solvent base adhesive 7701. 7701 is neo type adhesive, hardener solid content 100%, when you mix main agent and hardener, just put a little hardener, the standard ratio is 20:1. 1.It can do high working content and save solvent. 2.High green tack, good wetting ability, excellent coating performance. 3.Low viscosity, can do high speed printing.

Do you have the trouble that laminating small bag like PET/PE with solvent based adhesive is "high cost" and " not competitive but using solvent free lamination has " too high COF" and "film can not move smoothly on packaging machine" problem? Here is a special researched solvent free adhesive to just solve this COF problem with fast laminating speed, high bonding strength but low cof. Contact with us for more details.

Mono component solvent free polyurethane adhesive, specially used in laminating paper/film and paper/foil. This product has been formulated to give very high initial strength, high transparency and fast-curing. Nowadays Paper use more in our life, because paper is Biodegradable and environmentally friendly,along with it comes paper/film or paper/alu lamination develop fast. so adhesive apply in paper lamination develop accordingly. and mono component adhesive have to use solvent free laminator. now more and more customers have request for mono component. Contact us if you have any questions.

COF control of laminated roll film is important for automatic packaging processing. What we can do if the COF is higher than limit after aging? Following is a remedy method for your reference. -Slip agent: erucamide Erucamide is one of popular slip agents and used in film making. It can't solve in water, but can solve in EA solvent well. -Coating erucamide onto film Solve 300-350 g erucamide into 50-80kgs EA solvent coating it onto heat sealing side through dry laminator coating cylinder can be 200-250 LPI Drying tunnel temperature can be 40-50 degree. air inlet and exhaust are opened totally, don't use recycle air. - Low COF solvent free adhesive The important thing we should do is controlling COF at the beginning SL817A+SL817B -- Solvent free adhesive with low COF after lamination and aging. keep the COF low to 0.2 for 20u PE film lamination

Do you meet these problems before? 1. the laminated film can not move smooth on auto-packaging machine? 2. the auto-packaging speed is slow. 3. the surface of the package is too smooth to stacked up neatly 4. difficult to code the production date/expired date on package. All these problems are because of high cofficient of friction after lamination Normally following solutions can help to low the cof 1. using low curing temperature, and short the curing time, but should balance the cof and bonding strength. 2. keep the coating weight as low as possible, but also should make sure the appearance is beautiful, no bubble, no white spot. 3. keep the tension of winding as low as possible, but should pay attention to the bubble. Product recommendation. JOYA SL817A/B Specially researched solvent-free adhesive for thin PE film,easy to get a low cof.

For thickness over 60 micro PE film,normally it contains large slipping additives and anti-blocking additives. The slipping additives will migrate to film's surface to low the COF, to mare sure the films can move smoothly during bag making or packaging. But with the additives migrating, the bonding strength will decrease, even delamination . Adhesive solutions: SL817A/SL817B 1.Excellent additive resistance, keep bonding strength high. 2. Excellent heat resistance, bear 121 degree retorting treatment.

Quality of Metalized film control the adhesion of metalized layer on basic film Laminating Processing Dry coating weight keep 2.0-2.5g/m2 Increase the drying temperature 5-10 degree higher than normal Increase the air flowing speed in drying tunnel Do not use high temperature for aging/curing Adhesive Reduce the mixing ratio of -NCO hardener Using 40-45% high working solid content adhesive llike JYE7701A/B Using special metalized layer laminating adhesive to avoid transferring and high bonding strength like EM3175A/B

Application: DOYPACK, ALU contained zipper bag, Alu contained spout bag Laminating structure: PET/LLDPE, PET/VMPET/LLDPE, PA/PE PET/PA/ALU/LLDPE PET/VMPET/PET/LLDPE Adhesive: JOYA solvent base adhesive 5066 High enough bonding strength for alu foil lamination, to make sure the heat sealing area is still flat after zipper or spout adding Cost effective, medium to high performance Bear Alu foil pasteurization treatment.
