Abstract

The invention relates to the production of a high density polyethylene film in tubular form, for masking parts to be protected during painting and cleaning work and the like, whenever it is desirable to provide protection against aggression of various types. The HDPE film obtained by the methods of the invention has the following properties: it is transparent or faintly coloured; it can be manufactured so as to be a few microns thick; it can be cut manually, uniformly and very easily without tools, in a longitudinal and lateral direction; it can be manufactured so as to have different widths; it is stretch-resistant; it retains all types of projections such as paint, ink, soil etc.; it is printable; it can be applied on any substrate, independently of the state of its surface or the position thereof; and several adhesive strips can be provided on either or on both sides thereof, according to the needs of the user, thus avoiding the need for an additional adhesive strip. In addition to the above properties, the film has such properties as to make it suitable for protecting various items, such as in hygiene and food applications.

Description

DESCRIPTIF.DESCRIPTION.

L'inuention concerne la fabrication d'un film de masquage thermoplastique. Les différents traitements sont exécutés en continu sur une ligne de fabrication pour offrir les particularités suiuantes. The invention relates to the manufacture of a thermoplastic masking film. The different treatments are performed continuously on a production line to offer the following features.

Le déchirement longitudinal et latéral de façon régulière est réalisé par un dispositif d'extrusion soufflage (1), et de refroidissement.The longitudinal and lateral tearing is carried out regularly by a blowing extrusion (1) and cooling device.

La variation du débit de la matière en fonction de la tête annulaire (2), du taux de gonflage de la gaine13), de l'étirement et du refroidissement par flux d'air(4) permet d'obtenir un déchirement plus ou moins important, aussi bien dans le sens latéral que longjtudinal , dans des degrés identiques ou différents suiuant la qualité et l'épaisseur requise.The variation in the flow rate of the material as a function of the annular head (2), of the inflation rate of the sheath13), of the stretching and of the cooling by air flow (4) makes it possible to obtain a tearing more or less important, both laterally and longitudinally, in identical or different degrees depending on the quality and thickness required.

Le traitement de la surface micro rugueuse, pour obtenir l'adhérence des projections et vapeurs est obtenu par un rayonnement électriqlleí53 Le de9laça9e de la surface permet de créer des aspérités qui retiennent les particules projetées, tels que encres, peintures, souil'.ures
L'effet statique est réalisé par ionisation du film thermoplastique.The treatment of the micro rough surface, to obtain the adhesion of the projections and vapors is obtained by an electric radiation. The de9laça9e of the surface makes it possible to create asperities which retain the projected particles, such as inks, paints, stains.
The static effect is achieved by ionization of the thermoplastic film.

Des générateurs alimentant des harres de charges électrostatiques (6) placées trasesunrsalement par rapport au sens du défilement. Le traitement effectué uarie en fonction de la matière, de l'épaisseur du film thermoplastique et de l'effet recherché.Generators supplying harers of electrostatic charges (6) placed trasunrsally relative to the direction of travel. The treatment carried out depends on the material, the thickness of the thermoplastic film and the desired effect.

La bande de colle apposée sur l'une des facs est réalisée à froid par puluérisation d'un jet de colle (7) de façon continue ou discontinue. Elle peut être réalisée à chaud par imprégnation d'un tambour entrant en contact avec le film thermoplastique en permanence ou par intermittence (8).The strip of glue affixed to one of the facs is produced cold by pulverization of a jet of glue (7) continuously or discontinuously. It can be carried out hot by impregnating a drum coming into contact with the thermoplastic film permanently or intermittently (8).

Les deux procédés de pose de bande de colle sont employés en fonction du support, des uitesses de défilement des caractéristiques d'adhésion recherchées.The two adhesive strip laying methods are used depending on the support, the running speed of the desired adhesion characteristics.

Cette invention consiste à appliquer les différents traitements, pour obtenir le déchirement, la micro-rugosité, l'effet statique, et l'encollage sur un support thermoplastique en fabrication continue, en conseruant les propriétés intrinsèques de chaque traitement sans altération de leurs qualités. This invention consists in applying the various treatments, in order to obtain the tearing, the micro-roughness, the static effect, and the gluing on a thermoplastic support in continuous manufacturing, while preserving the intrinsic properties of each treatment without altering their qualities.
