摘要： PROBLEM TO BE SOLVED: To make biodegradation occur easily under a natural environment and also prevent leakage of deliquescent liquid or hydrogen chloride gas even in the use of a deliquescent chloride as a desiccant constituent, by employing a biodegradable resin having moisture permeability of a specific range. SOLUTION: The moisture permeability of a biodegradable resin that is molded into a film, sheet, container, or the like is specified to the range of 100-1500 g/m2 per 24 hours under an environment having a temperature of 40 deg.C and a relative humidity of 90%, preferably to the range of 300-1200 g/m2 per 24 hours, thereby controlling the moisture absorption speed of a desiccant. Specific examples of the biodegradable resin are a polyalkyl alkanoate resin, a polylactic acid resin, a polycaprolacton resin, a copolymer resin of 3- hydroxybutyric acid and 3-hydroxyvalerianic acid, a blend of starch resin and polyvinyl alcohol resin, and a blend of at least two or more kinds of the resins.

摘要： PROBLEM TO BE SOLVED: To provide a tape which is degradable when allowed to stand in the environment after use by applying a biodegradable pressure-sensitive adhesive to a biodegradable base film prepared from a biodegradable aliphatic polyester resin and a surface-treated filler. SOLUTION: This biodegradable pressure-sensitive adhesive tape is prepared by applying a biodegradable pressure-sensitive adhesive onto a surface of a biodegradable base film prepared from a compound comprising 100 pts.wt. of a biodegradable aliphatic polyester resin and 10 to 150 pts.wt. of a surface- treated filler. A biodegradable aliphatic polyester resin is selected from among a polycondensate from a polycarboxylic acid and a polyhydric alcohol, a ring- opening polymerization product of a cyclic ester and a polycondensate of a hydroxy acid. A biodegradable pressure-sensitive adhesive is prepared by compounding isobutylene rubber and natural rosin or the like. As a filler, use is made of an inorganic filler such as calcium carbonate, a ceramics balloon or the like which has been surface-treated with an epoxy silane or a titanate coupling agent, and an organic filler such as starch or the like which has been surface-treated with a surfactant such as acetylene glycol.

摘要： PURPOSE:To enable papers to be recycled without any necessity of the separation of a film from a paper on the innermost layer after being used while maintaining oil resistance by using a polyvinyl alcohol (PVA) films as an innermost layer of a laminated body whose base material is paper. CONSTITUTION:The polymerization degree of a PVA film used for this container is not limited especially, but that of P=500 to 3000 is preferable in workability. Also the saponification degree of the PVA is not limited, but it is preferable to use a complete saponification matter having the saponification degree of 99.0mol% or more in the case where an article to be packed is food. Moreover plasticizer like glyceline, lubricant like fatty acid or additive like talc can be added to the PVA film to such a degree that oil resistance is not decreased. It is necessary to use water soluble adhesive as adhesive for sticking the PVA film to the paper, the most preferable adhesive is a PVA adhesive. Thereby the innermost film and the adhesive are made of water soluble PVA resin, so that the paper can be recycled.
