A biodegradable wrap film simultaneously provided with cutting suitability, wrapping suitability, and heat resistance, in addition to biodegradability provided in lactic acid resin, is provided. The biodegradable wrap film contains a lactic acid resin composition as the main component and having a value of storage modulus at 40° C. in the range of 100 MPa to 3 GPa as measured at a frequency of 10 Hz and a distortion of 0.1% by the dynamic viscoelasticity testing method from Method A of JIS K-7198, a value of storage modulus at 100° C. in the range of 30 MPa to 500 MPa, and a peak value of loss tangent (tan δ) in the range of 0.1 to 0.8, was developed. This film displays excellent microwave oven suitability, in addition to resiliency and softness, and stretching and tensile strength suited for application in wrap film for household use.

摘要:
A process for producing a porous laminate having many micropores interconnected in the thickness direction, which comprises: a step in which a laminate is produced which comprises at least three layers comprising an interlayer made of a thermoplastic resin having a hard segment and a soft segment and two nonporous outer layers made of a filler-containing resin and located as outer layers respectively on both sides of the interlayer; a step in which the laminate obtained is impregnated with a supercritical or subcritical fluid and this state is relieved to vaporize the fluid and thereby make the interlayer porous; and a step in which the two nonporous outer layers located respectively on both sides are made porous by stretching.

摘要:
[Problem] To provide a heat-shrinkable laminate film, a molded product and a container, having excellent fracture resistance, rigidity, transparency after addition for regeneration, and in particular excellent shrink finishing quality. [Means for solving] A heat-shrinkable laminate film is drawn in at least one axial direction including at least three layers having an intermediate layer and front and back layers on respective sides of the intermediate layer. The intermediate layer is constituted by a layer composed mainly of at least one polystyrene-based resin. The front and back layers are constituted by layers composed mainly of at least one polyester-based resin. The front and back layers have a thickness ratio of 75% or less based on the total thickness of the film. The polystyrene-based resin is preferably a block copolymer. Further, preferably the heat-shrinkable laminate film has a birefringence index (Δn) of 1.0×10−3 or more and 80.0×10−3 or less. A molded product and a container is obtained by using the heat-shrinkable laminate film.

The present invention is directed to a catamenial tampon which includes a primary absorbent member and a withdrawal cord having a withdrawal portion and an attachment portion. The attachment portion is joined to the primary absorbent member. The withdrawal cord includes a composite yarn, which includes a continuous string, and a secondary absorbent member joined to a part of the continuous string. The continuous string is woven according to a predetermined weaving manner after being provisionally twisted, thereby forming the attachment portion and the withdrawal portion.
摘要:
To obtain a reflection film that does not undergo yellowing or a reduction in reflectance with a lapse of time by using, has excellent deadfold properties, generates less calorific when incinerated, and is degradable by microorganisms when subjected to earth filling, and causes no problem of waste disposal, the reflection film includes an aliphatic polyester based resin as a base resin and fine powder filler. The reflection film has pores inside thereof at a porosity of 50% or less. Preferably, the fine powder filler includes titanium oxide.
