It is specially used when the customer want to print complicated artwork in a vivid effect on kraft paper package. It works on the outside layer, however, no one is able to notice the film when it is closely laminated to the kraft paper material

Kraft Paper 60g, with brown color appearance, is the one of the most common used paper substrate film materials in flexible packaging field. Many coffee roasters choose the kraft paper materials out of environment friendly considerations.

LDPE 50, means low density polyethylene film, with thickness 50 microns, which is the most used inner sealing layer for the coffee bag. Actually, LDPE 50 is the lowest thickness applied for paper coffee packages. Sometimes, the customer may need a thickness inner LDPE film to achieve a stronger package.

The final thickness for this kraft paper foil laminate should be around 185 microns, with tolerance +-5%.  Upon our experience, kraft paper bag with this thickness would be a little tough, that may cause difficulty in the filling process.

Artwork Printing

A good creative artwork matters much more than most people expect, as most people tend to buy a product they feel good for.

For the printing produce in our plant, we are able to achieve the artwork in maximum 10 colors. With in-line print defect inspection system, more than 98% of the common print defects can be removed, you may have a further understanding by below video.

We will have to request a minimum order quantity of 10,000 bags against customer artwork. As to print each color, there will be a tank of printing inks offered to the rolling print cylinder. If we print only 5, 000 pcs, that will be huge waste of inks, film materials and labor.

So if the customer is just looking for hundreds or thousands of coffee bag, he is advised to take from the stock items, like matte white coffee bag or matte black coffee bag, that should be much more cost-effective than custom printed bag.
