发明名称 Dental packaging material and cartridge
摘要 A cartridge made of a material that does not to a significant extend absorb polar components from a dental composition stored therein. The force required to extrude a dental composition from the cartridge increases less over time in a cartridge of the invention than in a cartridge of the same configuration made of conventionally employed materials such as nylon-6.
