Abstract: A paper container includes a body and a contact layer. The body includes a bottom wall and a side wall. The side wall includes a covering portion and a supporting portion. An end of the covering portion surrounds the bottom wall so as to form an interior space. The supporting portion is integrally connected with the end of the covering portion and extends outwardly. The contact layer surrounds the covering portion. The contact layer includes a rugged inner surface and a fiat outer surface. The rugged inner surface includes a plurality of protruding portions formed thereon, and the protruding portions are adhered to the covering portion so as to form a plurality of air channels between the covering portion and the contact layer.

Abstract: A tamper-evident container is disclosed. The tamper-evident container includes a containing base, a lid, and a release structure. The containing base has a base edge and the lid has a lid edge. The lid is fixed to the containing base for closing and the base edge encloses the lid edge. The release is disposed at the containing base. The release structure includes a barrier line and two break lines. The break lines are extended from two ends of the barrier line to the base edge. A detachable zone is encompassed by the barrier line, the break lines, and the base edge. The break lines are for detaching the detachable zone from the containing base, so that the lid edge is partially exposed so as to separate the lid from the containing base.

Abstract: A tamper-evident container is disclosed. The tamper-evident container includes a containing base, a lid, and a release structure. The lid is fixed to the containing base for closing. The release structure is disposed at the lid or the containing base. The release structure comprises a break line and at least one hole. The hole is disposed on the break line and the break line is for separating the lid from the containing base.

Abstract: A biodegradable waterproof paper coated with PLA film and the manufacturing method for the same are disclosed. The biodegradable waterproof paper includes a PLA film on at least one surface of the paper and the PLA film partially infiltrates into the fibers of the paper.

Abstract: A biodegradable two-liquid type foaming composition, which comprises main liquid and auxiliary liquid, is disclosed. The main liquid is formed by mixing polylactic acid powder, polycaprolactone polyol and foaming agent. The auxiliary liquid is formed by mixing polyol and isocyanate. Once the main liquid and the auxiliary liquid are mixed, the foaming reaction proceeds and the biodegradable foam is formed.

Abstract: Biodegradable desiccant grains include 80-85 weight parts of a polylactide matrix and 20-30 weight parts of water absorbent particles dispersed in the matrix. The water absorbent particles include polysaccharide, biodegradable polymers, natural calcium carbonate, and activated charcoal. A method for making the biodegradable desiccant grains is also disclosed.
