Abstract
The invention relates to a mirror face plastic printing ink for an OPS (oriented polystyrene) thermoshrinkable film, which comprises 55-65 wt% of composite solvent, 10-18 wt% of composite resin, 20-26 wt% of pigment and 2-5 wt% of assistant, wherein the composite solvent is a mixture of ethanol, isopropanol, n-propyl acetate and propylene glycol monomethyl ether; the composite resin comprises a polyvinyl butyral resin as the main resin and an acrylic resin as the auxiliary resin; the pigment adopts ultrafine laminar aluminum silver slurry; and the assistant adopts a mixture of a setting agent and an organosilicon leveling agent. The environmental protection performance of the ink is controlled, and the non-toxic environmental-protection OPS thermoshrinkable film is matched to finally produce the recoverable novel skin packaging material which completely satisfies the requirement for environmental protection and is safe and non-toxic. By using the specific formula and production technique, the printed skin packaging has the mirror face effect, and can be used in high-grade packaging occasions with special requirements.
Description
Technical field
The invention belongs to the plastic printing ink technical field, relating to a kind of is that the no benzene that is used for the OPS heat-shrinkable film of the alcohol-soluble environmental type tool mirror effect of printed material does not have ketone mirror plastic printing-ink and preparation method thereof with novel environment friendly skin packaging material OPS (oriented polystyrene) heat-shrinkable film.
Background technology
Oriented polystyrene (english abbreviation is OPS) Shrink Film is a kind of novel skin packaging material of compliance with environmental protection requirements; It can not only print out exquisite pattern; Can also satisfy the use of the totally different novel package container of various profiles; Nonpoisonous and tasteless, but grease resistance is a kind of film that meets food hygienic standard.See by skin packaging Development of Materials trend; OPS (oriented polystyrene), PET environment-friendly materials such as (polyester) will progressively replace PVC (SE) heat-shrinkable film in recent years; Becoming the main flow of environmental protection package, is the ideal substitute that replaces the PVC Shrink Film.
The OPS heat-shrinkable film has following characteristics: 1, the feature of environmental protection: OPS can repeat to recycle, and cost recovery is low; Even used trade mark burned as the energy also can not produce any toxic gas, can not pollute to environment; Just because of chloride can't the burning (chlorine that burns the back generation can damage the ozone layer), even reclaim, because of the cost that reclaims is also bigger, and the Gold Content that utilizes once more is too low, loses more than gain for opposite PVC; With respect to the PVC heat-shrinkable film, the Gold Content that the OPS heat-shrinkable film utilizes once more is very high.2, highly shrinkable: because the OPS heat-shrinkable film adopts special production technique; Make that the shrinking percentage of OPS heat-shrinkable film is higher relatively; Its lateral shrinkage even can reach more than 80%, can let trade mark different shapes of containers (even single container dimensional differs bigger) go up realize evenly fit.3, the transparency: because OPS heat-shrinkable film particular chemical structure makes the OPS heat-shrinkable film that the good transparency and glossiness arranged; It is painted that this just determines that the OPS heat-shrinkable film is easy to, and can produce a lot of exquisite more trade marks.
Aspect printing-ink; Heat-shrinkable film plastic printing ink in the market generally can not satisfy the requirement of this novel skin packaging material of OPS; There are phenomenons such as printing effect is poor, sticking power is low; Therefore, there is not special special environment protection printing ink on the market to the exploitation of OPS heat-shrinkable film characteristics.Simultaneously,, on environmental-protecting performance, can not match, more can not realize the mirror effect of OPS heat shrinkable plastic film printing in the ink product the inside of environment-friendly type with OPS because heat-shrinking plastics printing-ink product contains benzene class and ketones solvent.
By traditional technology, on plastics film, realize the pattern of mirror effect, its method is to aluminize, its Production Flow Chart is: 1. full version is aluminized on film; 2. full version coating gloss oil on aluminium coated is done the Lacquer finish protection; 3. wash aluminium by the pattern requirement, pattern is not made the part of minute surface requirement and washed off, stay the mirror effect that part forms the pattern requirement.Use ink with mirror effect, can directly press the pattern printing, saved a large amount of resources, reduce cost about 80%, and the destruction that can avoid traditional technology that environment is caused.
The OPS heat-shrinkable film is a kind of novel environmental protection skin packaging material; It is nonpoisonous and tasteless; Therefore the printing-ink supporting with it must be the environment-friendly ink that can not contain benzene class, ketones solvent, because OPS has the transparency preferably, directly prints with printing ink of the present invention; Can reach mirror effect, to use in particular requirement, high-grade packing occasion.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art
,The present invention provides a kind of environmental-protecting performance through control printing ink; Arrange in pairs or groups the again OPS heat-shrinkable film of asepsis environment-protecting; Go out complete compliance with environmental protection requirements, safety non-toxic, callable novel skin packaging material with final production; Through specific prescription and production technique, make the skin packaging of printing reach mirror effect simultaneously, be implemented in particular requirement, high-grade packing occasion use be used for mirror plastic printing-ink of OPS heat-shrinkable film and preparation method thereof
