System for the production of a medical product, as well as method for operation of such a system
10531978 · 2020-01-14 · ·

A system for the production of a medical product, above all in the form of an ostomy bag, as well as a method for operation of such a system, uses a highly flexible modular system concept, in which individual feed lines for semi-finished products are provided. The feed lines can transfer semi-finished products to a main line in pre-assembled manner. In the main line, ultimate processing of the semi-finished products to produce the finished product or a further semi-finished product takes place, with the greatest possible work precision, in contrast to conventional systems that guide different film systems in different planes at a distance from one another, to allow pre-processing steps, before bringing the films together in one plane and welded to one another.

PACKAGING WITH SEALING MATERIALS HAVING DIFFERENT SEALING CONDITIONS
20240059466 · 2024-02-22 ·

Packaging material is provided. The packaging material can include at least one web layer having a surface that includes first and second regions. When corresponding first regions are overlaid with each other and corresponding second regions are overlaid with each other, the overlaid first and second regions can cooperatively surround a cavity. The packaging material further can include a first sealing material disposed in the first region and configured to seal together the corresponding first regions upon application of first conditions to the first sealing material, and a second sealing material disposed in the second region and configured to seal together the corresponding second regions upon application of second conditions to the second sealing material. The second sealing material can be configured such that the first conditions applied to the second sealing material are insufficient to cause the second sealing material to seal.

11975882 · 2024-05-07 ·

The present invention relates to a method and to a system for calibrating an automatic pouch forming machine. The present invention also relates to a device for characterizing a pouch precursor made of flexible heat-sealable film, said device comprising: a punch; a heat source for heating at least a tip of the punch to a given temperature; an actuator for pressing the punch against the pouch precursor made of heat-sealable film, with a given pressure; a measurement device for measuring the penetration of the punch in the pouch precursor, under the given conditions of temperature and pressure.

Cushion pad and packaging bag thereof

The present disclosure providing a cushion pad includes at least one cushion unit including at least one die-cutting region, a length of the die-cutting region increased when the die-cutting region is unfolded; the die-cutting region is unfolded to form a buffer layer that causes the second surface to expand in a thickness direction of the second surface to play a buffering and protective role thereof; the die-cutting region is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag with the cushion unit is of a plane structure after production; when the packaging bag is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion unit is expanded to form the buffer layer, to protect the object inside the packaging bag.
