Definitions
- the invention relates to the use of polyethylene terephthalate for the production of transparent packaging containers, in particular packaging tubes, formed by means of a welded longitudinal seam, and a tube formed from this plastic.
- Packaging containers are known, in particular, transparent bottles made of polyethylene terephthalate (short name PET), which have been widely used due to the good barrier effect of PET.
- Packaging containers are manufactured from the above-mentioned material by first injection molding a material blank as a semi-finished product. This blank is heated up during processing and placed in a mold corresponding to the shape of the container, in which the blank is inflated until the shape of the container is completely depicted.
- bottles made from the blank - also called injection-blown bottles - are crystal-clear (briefly transparent) and have no flow seams or similar shape-related surface impairments.
- transparent tubular packaging containers made of PET are also known.
- a blank is first injected, which is heated up during further processing and, in contrast to bottle manufacture, is not introduced into a blow mold but into a deep-drawing or stretching tool, in that the blank is made into a tube that can be filled at one end, consisting of a tube with a molded-on tube head , is reshaped.
- see-through tubes made in this way have the disadvantage of impaired transparency, which can no longer be classified as clear and transparent according to the quality feature. This is due to changes in the crystalline structure due to the deep-drawing and ironing process.
- the most serious disadvantage is that tubes made by deep drawing and stretching can only be decorated with a high level of printing effort.
- packaging containers produced in this way have to be rotatably decorated or printed while being received on a mandrel, in contrast to the printing of a flat strip of film which is subsequently formed into a tube.
- packaging containers manufactured by deep drawing and stretching, in particular tubes have the advantage of so-called "handling neutrality".
- "Handling neutrality” is understood to mean an unimpaired beta impression of the container by the user.
- No "handling neutral "of a container is present, for example, when the tactile or grip areas of a container have tangible surface deformations or impairments, for example weld seams, illustrated joints of molds, etc.
- the handling neutrality is "In addition to the mechanical-technological properties of a packaging container, this is a very important customer-oriented quality feature from the point of view of the packer.
- Tubes made of plastics are known, the tube tubes of which are formed from plastic film strips by longitudinally shaping the strip into a tube and welding overlying edge sections of the film strip. Tubes of this type are called longitudinally welded tubes. These tubes can be decorated with comparatively little expenditure on printing technology, since the film strips can be printed flat before the tube is formed. This is offset by the disadvantages that tubes with longitudinal seams cannot naturally achieve the quality characteristic of handling neutrality and the weld seam as such for plastics technicians and experts in the field of plastics welding, with certain reservations, depending on the type of plastics affected area remains.
- the invention aims to produce the same packaging container, namely a packaging tube by means of longitudinal seam welding, and to determine a plastic that can be used for this, i.e. to the task, which is solved by means of the features of claim 1.
- a longitudinally welded packaging tube is known, the tube of which is formed from three-layer plastic laminate.
- the laminate comprises a middle layer of PET planked on both sides with a layer of a polyethylene, the middle layer of PET fulfilling the function of a barrier layer and the polyethylene layers forming the weld seam, since polyethylene has a significantly better weldability than PET.
- EP 496 704 teaches the person skilled in the field of plastic tube production that PET can be used as a component of a multilayer laminate, but identifies this teaching in comparison to other plastics with weldability which is not readily achievable, so that the person skilled in the art does not readily resort to the use of the tube material used to solve the task according to the invention, taking into account the reservations which are relevant to him.
- tubes can be produced with the same transparency as injection-blown bottles, which can be colored and embossed with a comparatively low printing outlay (plan printing before tube forming).
- Handling neutrality is not completely achieved, however, in that the seam achieves a surface structure which blurs the key impression of a technically induced surface impairment in the tube user.
- the technically demanding welding itself did not result in intolerable material changes and swelling, ie extrusions; there were also no problems with regard to freedom from cracks and different diffusion barrier effects.
- FIG. 1 shows a first embodiment of a tube end in axial section with tube head and tube made of a plastic monofilm
- Fig. 2 shows a second embodiment of FIG. 1 with a tube tube made of a plastic laminate.
- FIGS. 1 and 2 are designated by 10 tube tubes, which are only shown in their head-side end region, which together with the heads designated by 11 each form part of a packaging tube.
- the head 11, also called the head part 11, is formed from a shoulder part 15 and a spout 16 with a spout opening 17, the spout 16 on its outer surface engaging means for one Tube closure, for example a thread.
- the head 11 is formed by pressing a plasticized blank by press molding.
- connection of the tube tube 10 and the formation of the head 11 is preferably carried out in one working step in that both compression molds are inserted into the tube tubes 10 at one end in compression molds, melted by radiant heat, contact heat or external heating and combined in the state with the heads forming in the compression mold.
- the head 11 according to FIGS. 1 and 2 can be equipped with diffusion-blocking devices 26 be equipped in the form of plate-shaped disks 18. These lie on the side of the shoulder part 15 facing the interior of the tube 11 and, in the embodiment according to FIG. 1, extend at one end from the tube end 19 to the inlet opening of the spout 16. In the embodiment according to FIG. 2, the plate-shaped disk overlaps 18 that brought into the shoulder part 15 Tube end 19, with which an increased tightness of the head 22 is achieved.
- the tube tube 10 consists of a film strip formed using PET, which has been bent around a mandrel to form a tube body and whose longitudinal edges and heating have been connected to compression and subsequent cooling to form a longitudinal weld seam.
- a film strip made of PET-G polyethylene terephthalate of the type designation G
- G polyethylene terephthalate of the type designation G
- Good, crystal-clear, transparent tubes with sufficient barrier effects were produced using the materials according to the invention, provided the film thickness was between 150 ⁇ m and 400 ⁇ m.
- the least conspicuous weld seams were visible and palpable if the overlap of the longitudinal film edges was between 0.5 and 1.0 mm, the welding temperature was between 180 ° C and 250 ° C and the pressing pressure at this temperature was set so that Material of the melted film edges visibly flow into one another in the overlap area.
- the material used according to the invention offers sufficient diffusion-inhibiting effects.
- the film of the tube tube 10 is designed as a three-layer plastic laminate, consisting of a layer 14, intermediate layer 12 and layer 13.
- the layer 14 made of PET-G forms the inner surface of the tube tube 10 after tube forming and welding, while the layer 13 made of PET-G forms the outer layer of the tube tube 10.
- the same materials for the layers 13, 14 are preferred according to the invention for good weldability of the edge sections of the film.
