How to keep cold laminator life longer

Details

Q:The machine's rollers are tighter on the sides than they are in the center which causes the material to feed through easier in the center than it does on the sides. Which causes the material to bow and start to wrinkle

A:You should lose the two screws so that the two rollers do not touch each other. if you tightened the two rollers together during the machine did not work, the two roller will lose their shape.

IF you forget it,  you can try to recover the two rollers, the solution is: you tightened the two rollers together and turn on the machine for one hour.

 when you laminate film, you should put the film into centre, means that left  sides should be equal to right side.

What types of tests should be performed to check film adhesion?

Details

 

Because there can be slight differences between different lot numbers of a roll of film or potential changes in adhesion properties after a splice, it is recommended to perform standard tests on the adhesion of the laminated film. The following are a few recommended tests:

The Tear Test
This is done by pulling the corner of the film away from the edge of the paper stock once it has cooled. Watch for the lamination pulling at the fiber of the paper. On some coated stocks, the laminate will pull ink directly from the sheet.

The Crease Test
This test is done by simply folding the laminated sheet and checking the adhesion in the crease. Look for any signs of the film releasing from the stock.

The Crush Test
This test is done by crumpling a laminated test sheet and then checking the adhesion in the same fashion as the crease test.

What amount of curing time should be allotted after laminating before moving onto other finishing processes?

What amount of curing time should be allotted after laminating before moving onto other finishing processes?

Although it is not always a feasible option in today’s ‘need it yesterday’ environment, it is recommended to wait a full 24 hours before sending the substrate onto the next finishing process. This will help improve the bond and should make it easier to emboss and/or diecut. Each operator will have to determine whether he/she needs to wait before continuing onto the next finishing state. Successful bonding will depend on the substrates and inks used combined with the environmental conditions.

What is the best way to store laminating films?

What is the best way to store laminating films?

All films should be stored in a cool, dry location away from direct sunlight and in the box it was shipped in, if possible. Also, consider using a first-in, first-out inventory system. Nylon should always be stored in a concealed wrapper to help maintain its inherent non-curl properties. Typically, summertime presents additional storage considerations. The higher humidity in certain regions of the United States will require partial rolls of film to be re-bagged to minimize the humidity’s effect on film. Another situation to be aware of involves the exposure of film to chemicals. Polypropylene has good resistance to chemicals – polyester and nylon do not. It is recommended to keep polyester or nylon as far away from the chemical source as possible to avoid exposure.
