Abstract
The utility model provides a thermal contraction nature E -PET complex film comprises extexine, tie coat and printing layer, is applied to the packaging material field. The tie coat is located between extexine and the printing layer, is in the same place an extexine and a printing layer bonding. The extexine be the LLDPE film, printing layer is the PETG film, the tie coat is styrene class segmented copolymer (SBC) resin. This film shrink wide range mainly is used for making the heat shrink sleeve mark, and the printing layer is as color designs's bearer layer, the mode of seal in the adoption. According to the condition of application, the thickness of this shrink film is adjustable, can adjust according to the condition of application shrinkage factor within the shrink upper limit. The utility model discloses have excellent shrink nature and printing performance, the manufacture craft is simple and convenient, comprehensive properties is strong.
Description
Technical field
This utility model relates to packaging material field, particularly relates to a kind of heat-shrinkable E-PET composite membrane.
Background technology
Heat shrinkage label belongs to sleeve label, be a kind of when adopting ink special to be printed on the film label labeling on heat shrinkable plastic film or plastic tube in a heated condition, shrink label will quickly shrink along the outline of container, it is close to vessel surface, builds the effect of " from top to bottom " comprehensive packaging bottle.
The heat shrink films being applied to packaging field at present mainly has polrvinyl chloride (PVC) heat shrink films, polyethylene (PE) heat shrink films, polystyrene (PS), PETG heat shrink films, multi-layer co-extruded Polyolefin Heat Shrinkable Film (POF) etc. 1) PVC heat shrink films printing performance is good, transparency is high, glossiness good, but shrinkage factor is generally not over 60%, and at some special-shape bottles or require that the application of high shrinkage (shrinkage factor more than 60%) field is limited, and PVC film contains plasticiser and can not recycle; 2) PE and POF heat shrink films pliability is good, and impact resistance, tear resistance are strong, not cracky, be not afraid of tide, contraction scope wide (shrinkage factor is the highest is adjusted to 80%), but printing performance is bad; 3) PS film and PETG film light transmittance and glossiness is good, shrink scope wide (shrinkage factor is the highest is adjusted to 85%) mechanical strength is big, printing performance good but the big hardness height of rigidity, the label feel made is poor.
Utility model content
For the deficiency that current heat shrink films exists, this utility model provides a kind of environmental protection, printing is good, contraction scope is wide, pliability good, soft handle, tearing toughness big, shrink uniform heat shrink films. According to applicable cases, the thickness of shrink film is adjustable, can be adjustable according to applicable cases shrinkage factor within shrinking the upper limit.
To achieve these goals, this utility model is to realize by the following technical solutions:
A kind of heat-shrinkable E-PET composite membrane, is characterized by: this heat-shrinkable E-PET composite membrane is A-B-C structure; Wherein A layer is extexine, is made up of LLDPE thin film; B layer is tack coat, is used for bond A layer and C layer, and tack coat is SBC resin bed;C layer is printing layer, and printing layer is made up of PETG thin film.
In layers of material, outer skin thickness accounts for the 30%-40% of composite membrane gross thickness; Adhesive layer thickness accounts for the 10%-15% of composite membrane gross thickness; Printing layer thickness accounts for the 45%-60% of composite membrane gross thickness.
This composite film thickness 40-80 ��m.
SBC used by tack coat (SBC) resin is butadiene styrene block copolymerization thing (SBS) resin.
Butadiene styrene block copolymerization thing (SBS) resin is the SBS of linear structure.
A kind of heat-shrinkable E-PET composite membrane, comprises the steps: in technical scheme
(1) composition structure: composite membrane is composited by extexine, tack coat and printing layer three layers curtain coating.
(2) rete composition: extexine is LLDPE thin film; Printing layer PETG thin film; Tack coat is SBC (SBC) resin.
A kind of heat-shrinkable E-PET composite membrane, SBC used by tack coat (SBC) resin in technical scheme, it is preferable that butadiene styrene block copolymerization thing (SBS) resin. When tack coat selects SBS resin, it is preferable that the SBS of linear structure.
A kind of heat-shrinkable E-PET composite membrane, in layers of material, outer skin thickness accounts for the 50%-75% of general thickness; Adhesive layer thickness accounts for the 10%-15% of general thickness; Printing layer thickness accounts for the 15%-35% of general thickness.
The beneficial effects of the utility model:
Providing a kind of heat-shrinkable E-PET composite membrane, extexine is PE film, and printing layer is PETG film. This kind of thermal contraction had both had the pliability of PE film, and puncture resistant ability is strong, and the advantage of soft handle has again the PETG film high grade of transparency, high gloss, excellent printing performance advantage.
This utility model E-PET heat-shrinkable composite membrane, utilize the PETG film contraction feature that scope is wide, printing is good, mechanical strength is high using PETG material as printing layer, in combination with the advantage that the good shrinkage factor of PE heat shrink films pliability is high, using PE material as extexine, binding material is utilized to be made by biaxial tension after curtain coating compound. The pattern that the heat shrinkage label that this kind of shrink film is made can be beautifully printed, has thermal contraction scope widely (shrinkage factor is maximum reaches 80%), and pliability tear resistance is good, and feel is splendid, promotes the appearance of packed article. After curtain coating compound, biaxial tension ensure that the shrinkage factor that PE layer is well consistent with PETG layer, solves because bi-material shrinks the inconsistent and problem such as wrinkling, the rete separation of face after the contraction that causes.
Accompanying drawing explanation
