Undoubtedly, we know how from the source of production to the end is. We have to trace the quality and check each step. We do if you need Quality Inspection Report.

In the process :

Cutting the paper into the size we need --> Printing --> Matte or Gloss laminated --> Creasing --> Hot Foil or Glitter or Flocking finishing --> Handmade work for Bag Body & Bottom & Handles  --> Inner & outer packaging.

Above the process, it's easy to generate the quality problems are Printing, Creasing, Hot Foil or Glitter or Flocking finishing and Handmade work for Bag Body & Bottom. 

Let's explain how to control and check:

1) Printing: Check the samples with artworks by German printing machine.

2) Creasing: Our worker fold the bag by creasing lines, if creasing lines can't be made by machine well, it'll be difficult for them to work, so the paper bags will be very ugly, unshaped and punch-drunk, especially the bottoms are rhombic and not rectangle. Thinner paper, easier happens.

3) Hot Foil or Glitter or Flocking finishing: Hot Foil machine's pressure determines quality, it's easy to make the foil uneven without suitable pressure; Glue determines glitter or flocking quality, bad glue makes glitter or flocking easy to fall out.

4) When handmade work for bag body & bottom, it needs to do by creasing lines, especially it's easy to scratch without the cloth on the workbench while doing paper bag with hot foil.
