摘要:
Coated articles may comprise one or more coating layers, including water resistant coatings. A method comprises applying such coating layers by treating the article substrate by one or more methods selected from flame treatment, corona treatment, ionized air treatment, plasma air treatment and plasma arc treatment and dip, spray or flow coating. Additionally, a method comprises injection molding a first substrate material to form an article, treating the article surface by one or more methods selected from flame treatment, corona treatment, ionized air treatment, plasma air treatment and plasma arc treatment, and overmolding the article substrate with one or more barrier materials.
摘要:
Récipient multicouche (1) en matière plastique apte à contenir un liquide. La paroi (2) du récipient (1) comprend, de l'intérieur vers l'extérieur de ce récipient (1): une première couche (10) en polyéthylène et qui présente sur sa face interne (15) une surface fluorée (16) obtenue par fluoration, une deuxième couche (20) qui est réalisée en matériau adhésif apte à solidariser la première couche (10) et une troisième couche (30), une troisième couche (30) qui est réalisée en polymère et apte à faire barrière à une pluralité de solvants et à l'oxygène, une quatrième couche (40) qui est réalisée en matériau adhésif apte à solidariser la troisième couche (30) et une cinquième couche (50), une cinquième couche (50) qui présente un taux de transmission de vapeur d'eau à 40°C et 90% d'humidité qui est inférieur à un seuil R o inférieur ou égal à 10,6 g.µm/m 2 /24h.
摘要:
Methods of making containers are provided, including providing a material sheet (200) having at least two barrier layers (204) and at least two polymer layers (202), forming the material sheet into a tube (312), sealing the tube at a seal area, and blow molding the tube to form a container in which the at least two barrier layers form a substantially continuous barrier at the seal area.
摘要:
Hollow injection molded article made of plastic material, esp. preform for blow molding a container, with a wall (17) extending along axis (Ι), which is composed of a layer of variable thickness (ε), being remarkable in that longitudinal ribs are provided in said axis direction, wherein the wall has a tooth profile of periodic nature varying periodically between a minimum and a maximum threshold value (m, resp. M) which is determined by a typical injection molding length (Ls) for said plastic material and/or characteristic ratio (εmax/εmin). A method of manufacturing thereof (10) by injection molding comprising forming inner and outer preforms (11, 12) with formation of an integrated composite preform (10), and apparatus for this purpose.
摘要:
A molded, low moisture vapor transmission plastic container is provided. The container includes a sidewall including an inner surface, an outer surface, a thickness and a first layer formed from a high density polyethylene resin. The container includes a bottom wall located at a lower end of the sidewall, and the bottom wall includes an inner surface and an outer surface. The inner surfaces of the sidewall and of the bottom wall define an interior contents cavity. The container includes a neck located at an upper end of the sidewall defining an opening into the interior contents cavity. The high density polyethylene resin acts as an effective moisture barrier limiting moisture transmission into or out of the container.
