An easily openable packaging material according to the present disclosure is a packaging material having a laminated structure including a paper base material, an anchor coat layer, a vapor deposition layer of a metal or a metal oxide, and a sealant layer in this order, in which the weight of the paper base material is 50% by mass or more based on the entirety of the packaging material, the thickness of the sealant layer is 2 to 40 m, the sealant layer includes a first polyolefin-based resin, and the tensile strength at break is 40 to 70 N/15 mm.

A bottle cap and a packaging bottle are disclosed. The bottle cap includes a cap (1) with a layered structure. The cap (1) includes a first layer (2), a second layer (3) and a third layer (4). The first layer (2) is an outer layer, the third layer (4) is an inner layer, the second layer (3) is an intermediate layer located between the first layer (2) and the third layer (4), and the second layer (3) includes at least one low oxygen-permeable barrier layer.

A pouch for holding a medical device. A base layer has a base periphery, a base back end and opposing base outer edges. A breathable first web is on the base layer and adapted to permit a sterilization gas to pass therethrough. A non-breathable middle film is adhered to the first web. A breathable second web is attached to the middle film, and a non-breathable top layer is over the base layer, thereby the pouch includes five layers. A primary seal adheres the base layer and the top layer. Then a secondary seal adheres the middle film and the second web to the base layer. The secondary seal is coextensive with the primary seal but then extends a partial width of the primary seal to thereby form a setback, wherein the setback allows the first web, the middle film and the second web to be formed in a single sealing step.

The current invention relates to a multilayer film. The multilayer film is characterized by a combination of desirable properties, such as excellent thermoformability, good optical properties, excellent sealability, puncture resistance and recycling capacity.

The present invention relates to a barrier-coated cellulose-based substrate (25a) and to a method of manufacturing such cellulose-based substrates, by dispersion coating of a ductile base layer pre-coating (12a) and subsequent dispersion coating of a gas barrier composition (13a) and/or vapour deposition coating of a barrier deposition coating (14a). The invention further relates to laminated packaging materials (20a) comprising the barrier-coated celluose-based substrate (10), in particular intended for liquid carton food packaging, and to liquid carton packaging containers comprising the laminated packaging material.
