A system and method for the continuous packaging of a confectionary product, such as cannabinoid confectionary products, by providing a packaging tray comprising a plurality of cavities, depositing a liquid confectionary product in each of the plurality of cavities, and overlaying a lidding material over the confectionary products to form a plurality of packaged confectionary products. The deposited confectionary product may be cooled or cured before or after overlaying the lidding material.

A cryogenic storage tank including a first metallic end piece having a first structured connection area on its outer surface, a second metallic end piece having a second structured connection area on its outer surface, a hollow body extending between the first structured connection area and the second structured area. The hollow body is formed of a fiber reinforced polymer-based composite, a first metallic clamp having a third structured connection area and a second metallic clamp having a fourth structured connection area. The hollow body is arranged between and in intimate contact with the first structured connection area of the first metallic end piece and with the third structured connection area of the first metallic clamp and is arranged between and in intimate contact with the second structured connection area of the second metallic end piece and with the fourth structured connection area of the second metallic clamp.

A multilayer structure includes a layer of a resin composition containing an ethylene-vinyl alcohol copolymer and a thermoplastic elastomer, wherein a mass ratio of the ethylene-vinyl alcohol copolymer to the thermoplastic elastomer is from 65/35 to 95/5 and the layer of the resin composition has one surface directly adjacent to a layer of polyolefin with no polar functional group. A multilayer structure is thus provided that is excellent in gas barrier properties, transparency, and flexibility and also has good delamination properties between the layer of the resin composition and the layer of the polyolefin with no polar functional group.

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.
