Definitions

  • the present invention relates to a stretch blow-molded or thermoformed pouch.
  • Pouches are well known in the art. Pouches are used as containers for food, beverage and nonfood products such as for example cosmetics, fragrances, personal care products, or detergents. Pouches are typically flexible containers which come in multi-dosage or single-dosage forms, and which can be easily discarded after use. Pouches are made of plastic foils or sleeves, or laminates thereof with co-extruded barrier (eg nylon) films, which are welded at the edges.

  • the neck of the pouch does not have to be taken into account.
  • a pouch By stretch-blow molding or thermoforming, a pouch is created which is seamless. Because of the absence of seams, the pouch 10 according to the present invention is less prone to rupturing during the manipulation (e.g. during filling), transportation, packaging and handling (by a consumer).
  • the pouch 10 can be blown in many shapes, and can vary from very flexible (bag-like) to more rigid.
  • the pouch is a self-supporting stand-up pouch 10, as shown in Fig 2.
  • the pouch is blown into a form such that the pouch comprises a base 50 that supports the pouch.

  • aseptic filling it may further be preferred to employ aseptic equipment. This allows the pouch to be used for food products requiring a long shelf life such as e.g. milk-based products.
  • the pouch is decorated. This can be done through conventional printing or labeling processes at the external surface of the pouch.
  • the pouch can be decorated in the mold (in-mold labeling).
  • thermoforming it is further possible to create a series of pouches, all thermoformed simultaneously and connected to each other e.g at their side walls, wherein the pouches contain the same products or alternatively, contain different products.
