Definitions
- the invention relates to a bag made of plastic film with a removal opening, which is relatively difficult to open and therefore sufficient for the contents Protection granted.
- a strip of the bag usually has to be cut off, since the sealed seams can only be opened while the material is destroyed. So-called peelable sealing seams are also known which can be opened but can no longer be closed.
- the bag is completely open in both cases and can no longer provide protection for the contents. The same also applies if a section of the folded plastic film is cut off in order to produce a removal opening.
- the invention has for its object a bag of the type mentioned to design that it is resealable even after the first opening.
- This additionally provided adhesive seam is when cutting or tearing the Bag is not damaged and is available for reclosing.
- the adhesive seam is a pressure-sensitive adhesive seam that, under pressure alone, defines the two Wall sections together.
- the application weight of the adhesive is about 1 to 20 g / m 2 .
- the invention of the adhesive strips has a width of at least 3 mm.
- FIG. 1 denotes a tubular bag, the jacket 2 of which along a Longitudinal seam 3 is formed into a tube.
- the lower end of the bag is by means of a not shown, transverse sealing seam closed.
- a transverse sealing seam 4 At the top of the bag is a transverse sealing seam 4 and at a short distance from it an adhesive seam 5 from a Pressure sensitive adhesive arranged.
- an upper edge strip is used, which forms the transverse sealing seam 4 includes cut off and then the pressure sensitive adhesive seam 5 is drawn. After The two jacket sections can be removed again from a partial quantity of the filling material placed on top of each other and the two sides of the adhesive seam pressed together.
- a stand-up pouch 21 is shown in FIG Cross seal 4 is closed. Below that also runs across the whole Stand-up pouch 21 an adhesive seam 5 made of pressure sensitive adhesive.
- the entire upper strip can be cut off with the transverse sealing seam 4.
- the adhesive seam 5 is then only in the appropriate length opened.
- FIG. 3 shows a sealed edge bag 31, which consists of a folded Foil cut is made along a longitudinal sealing seam 3 and two Cross sealing seams 4 is closed.
- a sealed edge bag 31 which consists of a folded Foil cut is made along a longitudinal sealing seam 3 and two Cross sealing seams 4 is closed.
- there is a The edge section with the one transverse sealing seam has already been cut off and the bag 31 only closed with an adhesive seam 5.
- This adhesive seam 5 can be used Removal of portions from the sealed edge bag 31 opened and again be closed.
- the material for the bags is primarily laminates, which are used for Suitable for storing non-sterilized food. These are, for example OPP / OPP, OPP / PE, PET / PE, PET / ALU / PE, OPA / PE, PET / ALU / PP, OPP / Paper / PE, Paper / PE or similar laminates.
- the adhesive is applied with a basis weight of 1 to 20 g / m 2 in a width of at least 3 mm.
