Description
Technical field
The present invention relates to shrink-packaging's material, particularly relate to a kind of means of heat-shrinkable film.
Background technology
In order to obtain metal effect on the packaging, often adopting blanching, cold wave, aluminize, washing the methods such as aluminium, packaging material obtain the metal pattern of local.
As Chinese patent literature CN101733776A a kind of gold stamping structure of stamping machine disclosed in the 16 days June in 2010, comprise plastic former upper template, described upper bolster bottom connects cope match-plate pattern by upper mould fixed plate, is also disposed with thermal insulation board and heating board between described upper mould fixed plate and described cope match-plate pattern; It is characterized in that: the contact surface of described thermal insulation board and described upper mould fixed plate has radiating groove.Realizing gold stamping by heating board and cope match-plate pattern is the gilding technology be most widely used at present.
For another example Chinese patent literature CN201408787 a kind of battery shrink packaging and a kind of film for battery shrink wrapping disclosed in the 17 days February in 2010.For a film for battery shrink wrapping, there is layer structure, comprise shrinkable film, inside shrinkable film, be also provided with patterned layer, clear coat, aluminium coated successively; The hot melt adhesive layer that the inner side of described aluminium coated is coated with when being also included in battery pack online.The technology that the document provides is the main flow realizing metal effect with aluminizer.
For another example Chinese patent literature CN101870209A planted the local aluminizing positioning printing method of packing film disclosed in the 27 days October in 2010, and the method comprises the following steps: (1) step, provides thin-film material; (2) step, vacuum aluminum-coated; (3) step, picture and text printing; (4) step, washes aluminium; (5) step, cleaning; (6) step, dry; The local aluminizing positioning printing method of this packing film, arranges aluminium coated by vacuum aluminum-coated mode on thin-film material, produces metallochrome, and then printing figure message wash aluminium, and aluminium coated protect not having printing-ink is washed off, generation metal luminous effect.Compared with existing gilding technology, the local aluminizing positioning printing method of packing film of the present invention, can work continuously, the intermittent action such as pressurize during without the need to protecting, and thus production efficiency is high; Simultaneously vacuum aluminum-coated cost is much smaller than gold stamping film.The technology that the document provides achieves local aluminizing and accurately locates with printing figure message, to imitate the effect that low cost and higher efficiency realize local aluminizing.
Although aforementioned metal effect packing technique realizes industrialization, and serves corresponding technique effect, but its Metallization effects is still imperfect, and tool has greatly improved space.When especially adopting means of heat-shrinkable film, by gold stamping, aluminize, wash Metallization effects layer that the modes such as aluminium arrange after thermal contraction, metallic luster can delustring, affects the displaying of Metallization effects.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art part and can not the means of heat-shrinkable film of delustring after a kind of thermal contraction is provided.
