Appearance quality refers to dust, holes, needle eyes, transparent points, wrinkles, folds, streaks, screen prints, wool marks, spots, pulp bumps, clouds, cracks, color inconsistency and other defects that can be observed by the naked eye.

Ii. jumbo roll sublimation paper 90gsm mechanical properties

Mechanical properties are also known as mechanical properties or strength properties, which are divided into static strength and dynamic strength.

1, static strength is the strength that the paper can withstand under slow stress, also known as the final strength. It includes the following quality indicators: tensile strength, breaking resistance, tearing, folding resistance, stiffness and so on.

2, dynamic strength refers to the strength of the paper can withstand instantaneous impact, which reflects the dynamic situation of instantaneous diffusion after the paper is stressed. Dynamic strength mainly includes the following indicators: puncture strength, ring compression strength, compression strength, etc., which is an important quality index of packaging paper and cardboard. - Printed envelope
