Food grade birch plywood Finnish M1 M2 M3 grade

Betula plywood can be divided into industrial grade and food grade according to its use. Here we are discussing food grade birch plywood, which is characterized by environmental protection grade according to Finnish M grade standard and European EN standard.

Food-grade birch plywood can be directly used in food processing industry as cushion board of food machinery, food furniture board, food packaging board. Finnish M-grade formaldehyde content is 0.05 mg/m2, 0.125 mg/m2 and 0.15 mg/m2, respectively. Strict environmental standards greatly improve the purity of plywood.

The raw material of plywood plywood for food-grade birch is the same thickness birch veneer made of Finnish super-grade birch, which has the advantages of uniform thickness, no wormhole, no black scar, no mineral line, no color difference and no splicing. Only with the above characteristics can we observe its level from the side to have a strong three-dimensional effect, one layer, one layer, clearly visible, this effect is the height that domestic plywood can not achieve.

Food-grade birch plywood has excellent mechanical strength in addition to its high environmental protection grade, which benefits from the high density of Finnish birch. Taking 12mm food grade birch plywood as a reference, the transverse compressive strength value is 27.7 mpa, and the longitudinal value is 24.3 mpa, which is far ahead of the similar birch plywood.

Fine production is the frontier position of manufacturing food grade plywood. Every process should fully guarantee the environmental hygiene of plywood, and pay attention to the hygienic condition of workshop according to the 24-hour dust removal standard of European Standard.
