Definitions
- the invention relates to a sealable plastic film for sealing packaging, which is constructed from a plastic carrier material and a sealing layer adhering to the carrier layer, and the advantageous use thereof.
- the sealing of packaging is essential for both food and pharmaceutical packaging in order to be able to influence the mechanical stability, the control of the water content as well as the influence of the atmosphere and light on the packaged goods.
- An important aspect, especially for tightly sealing containers for food, is to prevent microbial growth during the storage of the food.
- lid elements consisting of aluminum as the carrier material and a sealing wax, are used to close plastic containers.
- a multi-layer laminate is used as the carrier material, for example made of aluminum with plastics such as polyethylene terephthalate (PETP), polypropylene (PP), polyamide (PA) and even paper.
- PET polyethylene terephthalate
- PP polypropylene
- PA polyamide
- EP-A 590 461 it is therefore proposed to represent both the carrier material and the sealing layer uniformly with regard to their material components. Therefore, both in the carrier material layer and in the sealing layer finally used plastics.
- the plastics used in the carrier material layer are those based on polystyrene; the plastics used in the sealing layer are copolymers based on methacrylate which are relatively expensive to produce.
- the multilayer, heat-sealable plastic films disclosed according to EP-A 590461 are now easily recyclable and can also be subjected to mechanical loads, but can only be used to a limited extent, since their chemical structure in the seal layer means that they can only be sealed against polystyrene and polyvinyl chloride cups.
- the object of the invention is therefore to provide plastic films for sealing packaging, which are easily recyclable and mechanically stable, but at the same time are satisfactorily heat-sealable regardless of the material component in the package used.
- a sealable plastic film of the type mentioned is proposed, which is characterized in that the plastics of the carrier material in a mixture consisting of polystyrene (PS), at least one polyolefin, a styrene-butadiene-styrene three-block copolymer (SBS) and / or a styrene-butadiene elastomer (SBR).
- PS polystyrene
- SBS styrene-butadiene-styrene three-block copolymer
- SBR styrene-butadiene elastomer
- the sealable plastic film according to the invention also has the advantage that the proportion of polystyrene is 5-90% by weight, the proportion of polyolefin is 90-5% by weight and the proportion of styrene-butadiene-styrene triblock copolymer and / or styrene-butadiene Elastomer at least 5% by weight, based on 100% plastics in the carrier material.
- Another advantageous feature of the sealable plastic film is that the polyolefin is present in the carrier material in the form of a polypropylene (PP).
- the sealable plastic film according to the invention is characterized in that the molecular weight of polystyrene in the carrier material mixture is at least 100,000.
- the styrene-butadiene-styrene three-block copolymer and / or the styrene-butadiene elastomer are modified by adding polymeric compounds selected from the group consisting of polyamide (PA), polyethylene terephthalate (PET), polybutylene terephthalate ( PBT), polyphenyl ether (PPE), polycarbonate (PC), polyvinyl chloride (PVC).
- PA polyamide
- PET polyethylene terephthalate
- PBT polybutylene terephthalate
- PPE polyphenyl ether
- PC polycarbonate
- PVC polyvinyl chloride
- the sealing layer is advantageously a synthetic resin based on ethylene vinyl acetate (EVA), styrene-butadiene-styrene three-block copolymer (SBS), styrene-butadiene elastomer (SBR), an acrylic synthetic resin, a polyvinyl chloride (PVC) or a polypropylene copolymer resin.
- EVA ethylene vinyl acetate
- SBS styrene-butadiene-styrene three-block copolymer
- SBR styrene-butadiene elastomer
- acrylic synthetic resin a polyvinyl chloride (PVC) or a polypropylene copolymer resin.
- the total thickness of the sealable plastic film is advantageously in a range from 20 to 200 ⁇ m, the layer thickness of the carrier material layer being 5 to 95% and the thickness of the sealing layer being 95 to 5% of the total thickness.
- Another advantage of the invention is that the thickness of the carrier material layer is 85-95% and the thickness of the sealing layer is 5-15% of the total thickness of the plastic film.
- an adhesion promoter layer is advantageously provided between the sealing and carrier material layers.
- the sealable plastic film according to the invention is advantageously used as a cover element for cups, especially yoghurt cup or used as a sealing film for pharmaceutical packaging, in particular blister packs.
- polystyrene 70% by weight of polystyrene, 10% by weight of polyolefin, for example polypropylene, and 20% of styrene-butadiene-styrene three-block copolymers are mixed.
- the polystyrene used has a molecular weight of approximately 200,000. It can be modified, for example, by monomer units based on styrene-butadiene-styrene or styrene-butadiene elastomer. Polypropylene, for example, is used as the second component. These two components would not be miscible per se, so that the styrene-butadiene-styrene used, for example, serves as an intermediary between the two mixture components. As a result, these properties of the mixture, such as, for example, its heat resistance, as well as its rigidity and expansion coefficient, can be influenced for a given further processing of films.
- the above-mentioned exemplary mixture for the carrier material in granular form is introduced into a main extruder.
- the components of the carrier material mixture are presented in such a way that an 80 ⁇ m thick carrier material layer is produced after appropriate stretching.
- the starting material is component for the production of the sealing layer, for example ethylene vinyl acetate.
- the entry is made in such a way that a 20 ⁇ m thick sealing layer is produced after appropriate stretching.
- a heat-sealable plastic film according to the invention is therefore produced in a thickness of, for example, 100 ⁇ m in the coextrusion plant.
- a carrier material layer with a thickness of 80 ⁇ and a sealing layer with a thickness of 20 ⁇ are now optionally produced in separate extrusion processes. Both foils are glued to a composite foil by means of an adhesive, for example from one or two-component reaction systems.
- Lids are now punched out of the plastic film according to the invention and these are sealed on yoghurt beakers, for example polystyrene beakers, at a sealing temperature of 180 ° C., a sealing pressure of about 1 bar and a sealing time of 0.5 sec.
- the cups are tightly closed and can still be opened easily.
- the seal seam strength is accordingly 5 - 20 N.
- the plastic film according to the invention can be sealed onto pharmaceutical packaging known per se under the aforementioned sealing conditions.
- the sealed strips can be easily peeled off so that the medication pack can be opened easily.
- the plastic film according to the invention is therefore suitable both as a cover element for cups such as yoghurt cups and as a sealing film for pharmaceutical packaging such as blister packs.
