An environmental protection paper material structure for food containers
and its manufacturing method include a paper layer roll printed and
coated with a first crosslinker coating in compliance with the laws and
regulations of an adhesive for food packaging on both surfaces by a roll
printing method, and a biodegradable material layer coated on the surface
of the two first crosslinker coatings by a film coating method, and a
second crosslinker coating and an anti-adhesive coating roll-printed and
coated on upper and lower external layers. The anti-adhesive coating at
the external layer effectively prevents the biodegradable material layer
from being in a direct contact with the moisture in the air or becoming
sticky due to a temperature rise before the environmental paper material
is cut into different shapes of paper containers or rolled or stacked for
storage, and the paper material can be used directly for hot pressing and
shaping.
