Method for producing a plastic foil with a non-stick coating and a package

p0001The invention relates to a plastic film with a nonstick coating, particularly silicone, for the manufacture of a wrapping packaging with embossed edge closure strip.

p0002There are known such plastic films, but they all have the disadvantage that embossed closure strips can be very difficult and only with special methods, usually a complicated process needle manufactured.

p0003The invention addresses the problem of proposing a plastic film for wrapping packages, which can be marked safely and easily with standardized procedures.

p0004This object is achieved in that portions of the film, in which the embossing is provided, are cut from the non-stick coating.

p0005This makes it possible, in that region, which has no anti-adhesive coating to apply an embossed closure strip.

p0006It has proved to be advantageous if the recesses are arranged on the non-stick coating is substantially transverse to the transport direction of the film.

p0007This can be produced for wrap packaging easily continuously film sections.

p0008It is also advantageous if markers are attached to the control of the coating with anti-adhesive agent to the foil in defined intervals.

p0009Thus, it is possible to realize a very accurate control of the non-stick coating and uncoated areas of the film.

p0010Another advantageous feature is the fact if at least two non-stick coating-free portions of the film are connected to each other.

p0011This provides a further improved sealing of the wrapping packaging is ensured.

p0012It is also advantageous if the connection of the sections is designed as a so-called Verkrümperung, in which a plurality line-shaped individual embossments are provided.

p0013Thereby a secure holding together of the joined portions is ensured.

p0014Furthermore, it is advantageous if the connection of the sections is configured as a seal.

p0015In sealable films herewith a secure connection of the sections with each other is produced.

p0016In the drawing the invention is illustrated using an exemplary embodiment. They show:<dl id="dl0001"><dt>Fig.1</dt><dd>a sheet for producing a wrapping packaging and</dd><dt>Fig.2</dt><dd>a wrapping packaging made of a film section</dd></dl>

p00171 with a film web is indicated in Fig.1, having a non-stick coating of silicone in subregions second Other sections 3, which lie between the areas 2, are omitted from this siliconization. For applying the siliconization in the first part of areas 2 on the film web 1, to control positioning and scanning markers 4 are provided on the film web first

p0018To form a wrap package 10, the sheet 1 is cut along lines. 5 Any resulting portions 6 are then wrapped around a object to be packaged and 11 mi area of ​​the recesses 3 verkrümpert the overlapping layers of 6 sections each.

p0019This Verkrümperung 12 consists of individual line-shaped embossing, which detect both layers and connect to each other.
