Abstract
The present invention is PTP bubble plate paper for medical and food product and its production process. The PTP bubble plate paper includes lower layer of wax adhesive, middle layer of high density medical and food product paper, and upper layer of PVDC paint layer. The production process includes the steps of: selecting high density packing paper, printing, painting PVDC on the surface of paper, re-painting EVA to the back side, stoving and cooling. The packing paper of the present invention has high blocking performance and low production cost, and is suitable for the PTP bubble plate packing of medical and food product.
Description
Technical field
The present invention relates to PTP bubble-cap paster paper and production method thereof, particularly relate to a kind of medical and edible PTP bubble-cap paster paper and production method thereof.
Background technology
Medical and food uses the scope of application of PTP blister package wide, the PTP paster material mainly was to use aluminium foil in the past, this material, although its barriers function is superior, exist many hidden danger in the actual mechanical process, be embodied in: aluminium foil (generally being 25mm-35mm) is after the automatic packaging machine packing, near bubble-cap, be easy to generate a large amount of pin holes, like this, functions such as the waterproof of aluminium foil, surface of air permeation preventive reduce greatly, have stayed hidden danger; And aluminium foil PTP paster is because its embrittlement is apparent in view, consumer person use or acquisition process in, because warpage, the embrittlement that action causes the adjacent blister paster such as peel off, influence the shelf characteric of packing material especially easily; In addition, the production of aluminium foil and typography complexity, the cost height, polluting big the grade all is the apparent in view defective of this product!
At this state, the inventor has dropped into great amount of manpower and material resources, and Related product has been carried out long term studies and test, has obtained the invention achievement that replaces aluminium foil with paper substrate finally, and this achievement has good technique effect and economic benefit.
Summary of the invention
The purpose of this invention is to provide a kind of wrapping paper that replaces aluminium foil as the PTP paster, PTP smt package paper of the present invention is suitable for all kinds of automatic packaging machines to be used.
Another object of the present invention provides the production method of above-mentioned PTP smt package paper.
The object of the present invention is achieved like this, a kind of PTP smt package paper, and this wrapping paper comprises the wax adhesive of lower floor, PVDC (polyvinylidene chloride) coating layer on the high density of middle one deck medical or edible paper and upper strata.
Another object of the present invention is to realize like this, the production method of PTP smt package paper of the present invention, the following technological process of adopting, select highdensity medical or edible wrapping paper → printing → coating → coating → oven dry again → cooling for use, it is characterized in that the described coating first time is to coat PVDC (polyvinylidene chloride) on the surface of paper, coating is at the back side of paper coating wax adhesive again.
Technical scheme of the present invention comprises that described PVDC selects the PVDC emulsion of quick-dry type for use, and coating weight is 6-12g/m
2
Technical scheme of the present invention comprises that described PVDC coating weight is 8g/m
2
Technical scheme of the present invention comprises that containing EVA (ethylene-vinyl acetate copolymer) in the described wax layer is 20%-30% (weight ratio), and its coating weight is 10g/m
2
Technical scheme of the present invention comprises that described stoving process adopts the segmentation heating mode.
Technical scheme of the present invention comprises that the chill roll diameter is greater than 350mm in the described process for cooling, and chilling temperature is 0 ℃-10 ℃.
The invention has the beneficial effects as follows:
1, the paper by the PVDC coating has goodish barrier property, can remedy the defective of the barrier property aspect of paper like this.
2, the relative aluminium foil of paper printing is more exquisite, more convenient, and cost is lower.
3, the technological requirement condition of this production method is not high, only needs common compounding machine is done some adjustment, finishes at normal temperatures and pressures.
4, the cost of entire product is compared with aluminium foil greatly and is reduced, and possesses suitable environmental-protecting performance.
Description of drawings
Fig. 1 is structural section figure of the present invention.
Among the figure, the 1.PVDC layer; 2. paper substrate; 3. wax layer
The specific embodiment
As shown in Figure 1, PTP smt package paper of the present invention is divided into three layers, and the upper strata is a PVDC coating 1, and general coating thickness is 6 μ m, and coating weight is 6-12g/m
2, middle one deck is for being suitable for high density wrapping paper 2, and wrapping paper is 50-70g, and all there is production in a lot of producers in Europe, and paper substrate can not contain fluorescer and meet the FAD standard, and lower floor is an adhesive wax layer 3, and thickness is 12 μ m.
A kind of specific embodiment of PTP smt package paper of the present invention is as follows:
1, adopts the high density medical packing paper of 60g.
2, the character pattern of printshop need.
3, coating PVDC: select quick-dry type PVDC for use, coating weight is 8g/m
2, the quick conjunctiva temperature of PVDC emulsion be 80 ℃-100 ℃ promptly available.
4, coating adhesive: selecting coating wax for use is adhesive, and wherein the content of EVA is 25% (weight ratio), helps the heat seal of paper and plastics.
5, oven dry: adopt the segmentation heating mode, setting drying rate is 60 meters/minute, and then drying channel is set two baking stages, is set at 70 ℃-80 ℃ and 95 ℃-100 ℃ respectively.Notice that drying time can not be long, temperature can not be too high, embrittlement occurs, phenomenons such as jaundice after avoiding negative paper to lose moisture content.
6, cooling: through 4 ℃ chill roll, the diameter of chill roll is greater than 350mm after the oven dry.This chill roll diameter is the bigger the better, and chill-roll temperature is less than 10 ℃.
7, cut: adopt dise knife to cut, avoid end face to produce burr.
8, packing: can use the health plastic dress to tighten sealing during packing.
