A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

Provided are a multilayer film having excellent gas permeability and excellent handling properties and hence is suited for forming a cell culture container, and a cell culture container formed by using the same. A multilayer film used for forming a cell culture container, comprising: a base material composed of a polyethylene-based resin having a density of 0.87 g/cm.sup.3 to 0.90 g/cm.sup.3; and an inner layer composed of a polyethylene-based resin having a density of 0.896 g/cm.sup.3 to 0.93 g/cm.sup.3 and forming a cell culture icy surface. A cell culture container is formed by using this multilayer film.

Filter media and media packs that provide robust performance in high-speed rotating coalescer (HSRC) elements for crankcase ventilation systems are described. The fiber media is HSRC fiber media. As such, the filter media has a higher resistance to compressibility then traditional coalescer filter media, such as fiber media used in low-speed rotating coalescer arrangements or stationary coalescer arrangements.

A polyester film laminated with other polymers to form a sheet. A laminated tube for liquid and paste products such as toothpastes, and the like can be manufactured from said sheet. The laminate comprises an outer polyethylene film, adhesive agent layers, a polyester film, and a composite polyethylene film comprising at least one co-extruded polyethylene layer sandwiched by at least one polyethylene film and an inner polyethylene film.

The present invention provides a structure that improves sound absorption coefficient. The present invention provides a structure comprising: a foam resin layer formed of a foam material having a foaming ratio of 1.1 to 8 times; and a sound absorbing layer formed of a foam material having a foaming ratio of 10 to 30 times, the sound absorbing layer laminated on the foam resin layer.
