Abstract
The invention provides a PVA high-blocking water-based coated film, which comprises a PE film, wherein the PE film is provided with PVA coated liquid; after the modified PVA coated liquid of 2 mu m iscoated on the PE film, the oxygen-permeating filter of the film is less than 1cm[3](m<2>.24h.0.1MPa), and is even less than 0.5cm[3](m<2>.24h.0.1MPa), so the coated film has the characteristics of excellent processing performance, high transparency, content resistance, no toxicity, no pollution, degradation and the like, and can be widely used for various liquid state milk packages. When the coated film is used, printing ink and adhesives are positioned at the outer layer of the PVA coated liquid, and thus, residual solvents in the printing ink and the adhesives cannot enter in a packaging bag to pollute fresh liquid milk. The PVA high-blocking water-based coated film is an environment-friendly packaging material.
Description
(1) technical field
The present invention relates to a kind of packing, be specifically related to a kind of high-barrier water-based coated film.
(2) background technology
Plastic package material removed and to satisfy client's quality 21 century, outside the requirement that time of delivery, service etc. improve day by day, also must develop to directions such as the recycling economy of environmental protection, high in technological content, sustainable development, safety.The enterprise that uses packing extends the shelf life in order to guarantee the requirements for quality of content at present, the mode of the general sterilization of adopting.
(3) summary of the invention
The object of the present invention is to provide a kind of excellent processing performance, high transparent, anti-content, nontoxic, pollution-free, degradable PVA high-barrier water-based coated film.
The object of the present invention is achieved like this: it comprises the PE film, and the PE film is provided with the PVA coating fluid.
The present invention also has some technical characterictics like this:
1, described PVA coating fluid is 2um;
2, the skin of described PVA coating fluid is provided with printing ink and adhesives.
Beneficial effect of the present invention has: the present invention is behind coating 2um modified PVA coating fluid on the PE film, and the oxygen flow filter of film is less than 1cm
3(m
224h0.1MPa), even less than 0.5cm
3(m
224h0.1MPa), have characteristics such as excellent processing performance, high transparent, anti-content, nontoxic, pollution-free, degradable, can be widely used in various liquid milk-packings, time spent, printing ink and adhesives are all at the skin of PVA coating fluid, so the residual solvent in printing ink and the adhesives can't enter packaging bag internal contamination fresh liquid milk, is a kind of environment-friendly package material.
(4) description of drawings
Fig. 1 is a structure principle chart of the present invention.
(5) specific embodiment
The present invention is further illustrated below in conjunction with the drawings and specific embodiments:
In conjunction with Fig. 1, present embodiment comprises PE film 1, and the PE film is provided with PVA coating fluid 2, and the PVA coating fluid is 2um; The skin of PVA coating fluid 2 is provided with printing ink and adhesives 3.
Claims (3)
1, a kind of PVA high-barrier water-based coated film, it comprises the PE film, it is characterized in that the PE film is provided with the PVA coating fluid.
2, PVA high-barrier water-based coated film according to claim 1 is characterized in that described PVA coating fluid is 2um.
3, PVA high-barrier water-based coated film according to claim 1 and 2 is characterized in that the skin of described PVA coating fluid is provided with printing ink and adhesives.
