Abstract
The present invention relates to sheet for packing food and medicine, and belongs to the field of shaped packing material. The sheet for packing food and medicine has basic material layer of non-crystalline polyethylene terephthalate, and has high obstruction performance on oxygen, water vapor, and smell of food and medicine, high mechanical strength, good thermal sealing performance, high thermal sealing strength, and high chemical stability without reaction with acid, alkali, salt, solvent and oil. The sheet for packing food and medicine coincides with the requirement of food sanitation, is harmful to human body, can be recovered for reuse. The present invention may be used widely in making food and medicine packing container.
Description
Technical field
The present invention relates to article packing section bar, particularly food, drug packaging section bar.
Background technology
At present, food, drug packaging are common with the substrate layer of sheet material to be polyvinyl chloride layer, though pvc material has characteristics such as flame resistance, flame resistance, bright in luster, withstanding corrosion and firm and durable, but, its vinyl-chloride-containing is a carcinogen, add some poisonous auxiliary substances such as plasticizer, stabilizer, ageing resistant in its manufacturing process, can discharge toxic substance during burning.Therefore, food, the drug packaging made of polyvinylchloride base material layer have certain toxicity with sheet material, and can discharge noxious gas when reclaiming, and environment is polluted.Owing to above reason, need to seek food, the drug packaging sheet material of the substrate layer that substitutes polyvinyl chloride layer.
Summary of the invention
The purpose of this invention is to provide a kind of food, drug packaging sheet material, packing container splendid attire food, the medicine made of sheet material of this food, drug packaging, have nontoxic, recyclable, better oxygen barrier, water proof steam, intensity is good and characteristics such as glossy, the food of interior Sheng, medicine are difficult for oxidized going bad.
Technical solution of the present invention is that food, drug packaging are non-crystallization polyethylene terephthalate layers with the substrate layer of sheet material.
Above-described polyurethane adhesive articulamentum can be two-component-type polyurethane glue-line or one-pack type polyurethane glue-line.
The coating weight of polyvinylidene chloride barrier layer of the present invention can be 3～60g/m
2
The coating weight of polyurethane adhesive articulamentum of the present invention can be 0.1～10g/m
2
Substrate layer material therefor APET sheet material of the present invention is extruded through the T pattern with the PET material and is made, and the fusion PET material of extruding through the quenching typing in flakes.Resin has little time crystallization, is in unformed state, makes the sheet material that finally makes have the fabulous transparency, has also kept some other advantage of PET material simultaneously.The main performance advantage of APET is high light transmittance, low oxygen durchgriff (its oxygen permeability only is half of PVC material), nontoxic, oil resistant, resistance to chemical attack, recyclable, does not produce pernicious gas in the recovery.The mechanical characteristics, barrier property and the printing performance that have kept the PET material in addition.The leftover pieces of APET sheet material can make full use of, thereby can of low pollution, and cost-cutting.Therefore, the APET sheet material becomes the packing of comparatively desirable alternative PVC.The forming characteristics of APET container and PVC sheet material are approaching, can adopt conventional thermal forming device forming work and need not acquire specialized equipment, and when adopting the APET container to replace the PVC container, even used mould can intactly utilize former PVC sheet forming the time.
Performance Detection project of the present invention and testing result are as follows:
| Test item | Unit | Standard | Testing result |
| The vapor permeation amount | g/m 2·24h | ≤2.5 | 1.9 |
| The oxygen transit dose | cm 3/m 2·24h·0.1Mpa | ≤10.0 | 4 |
| Heat sealing strength | N/1.5mm (in length and breadth to) | ≥8.5 | 12 |
| Vinylidene content | mg/kg | ≤3.0 | 0.1 |
| Heavy metal | Mg/l (in pb) | ≤1.0 | 1.0 |
| Easy oxygen thing | ml | ≤2.0 | 0.85 |
| Solvent Disabled storage | mg/kg | ≤10.0 | 3.0 |
| Water | mg/l(120℃0.5h) | ≤30.0 | 8.5 |
| 65% ether | mg/l(70℃2h) | ≤30.0 | 5.5 |
| Normal hexane | mg/l(58℃2h) | ≤30.0 | 5.0 |
Advantage of the present invention be food, drug packaging with sheet material to oxygen, aqueous vapor, and the smell of food, medicine has very high barrier; Mechanical strength is good; Heat sealability is good, easily heat-sealing, and higher heat seal strength is arranged; Chemical inertness is good, with acid, alkali, salt, solvent, grease chemical reaction does not take place; Meet the food hygiene requirement, nontoxic to the people; Recyclable utilization can not pollute environment.The packing container intensity of making of the present invention is big, light transmission good, nontoxic, good barrier property, and recyclable utilization.
Description of drawings
Fig. 1 is an organigram of the present invention.
The specific embodiment
According to shown in Figure 1, the present invention includes substrate layer 1, articulamentum 2, barrier layer 3.Substrate layer 1 is noncrystallineization polyethylene terephthalate layer, i.e. APET layer.The APET material is that the PET material is extruded through the T pattern and made, and its thickness is 0.05mm to 2.8mm.Present embodiment selects thickness 0.5mm, width 750mm.Articulamentum 2 on substrate layer 1 is adhesive coatings of the bi-component solvent borne polyurethane glue of coating, also can be the adhesive coating of one-pack type polyurethane adhesive, and its coating weight is 0.3g/m
2Different as requested, the scope of its coating weight is 0.1～10g/m
2Barrier layer 3 is that to be coated with polyvinylidene chloride (PVDC) with coating machine on articulamentum 2 be the copolymer emulsion of vinylidene chloride and vinyl chloride, and drying is coated with and forms, and its coating weight is 15g/m
2Different as requested, the scope of its coating weight is 3～60g/m
2Food of the present invention, drug packaging processed on plastic molding press with sheet material can be made into various food, drug packaging container.
