新型钦料瓶口密封设计消除卫生隐患

胶瓶装饮料一直以其良好的储存性能与反复使用性吸引着消费者，不少人甚至将饮料瓶用于存放日常调味品，但当前通用瓶盖设计可能存在缺陷，并能直接导致饮料“二次污染”——瓶口螺纹部分和瓶盖长霉。这是封口结构存在一定的缺陷性。事实上，目前使用的塑料饮料瓶封口结构，并不能保护瓶口螺纹部分的卫生，因为瓶口螺纹部分并非是被密封保护的。关于PET瓶口容易长霉的问题，目前是困扰饮料行业的一大难题，     

废瓶新用

打开包装的食物不密封好容易受潮变质，手匀可以利用空饮料瓶来带作一些封口器，把饮料瓶从靠近瓶盖的地方切开，饮料瓶的前半部就变成了封口器，把塑料袋从瓶口穿过再打开，然后把覆盖了塑料袋的瓶口拧上瓶盖，整个密翊过程就完成了。这个封口器还可以循环使用，剩下的后半部分瓶身也可以放在冰箱门上做成收纳罐。     

酒瓶瓶口密封衬垫纸技术总结

一、前言酒瓶瓶口密封衬垫纸(下称衬垫纸)的研制任务系四川省轻工厅八二年轻工业科学研究计划下达的。八三年接转重庆市科委。主要目的是研制用复合纸代替目前螺纹口类酒瓶广泛采用的瓶口密封材料——内塞及胶套。这种复合纸具有良好的密封性能。使用方便,价格便宜等优点。国外,酒类的包装有桶装、罐装、坛装、瓶装及盒装等多种形式,封口材料也各异。但市场销售仍以瓶装为主,就瓶装而言,仍以螺纹口玻璃瓶为主。封口材料一般都使用密封衬垫。其特点是密封性能好,使用方便,重复开闭仍能保持密封。

SiOx layer as functional barrier in polyethylene terephthalate (PET) bottles against potential contaminants from post-consumer recycled PET

The barrier effect of a silicon oxide (SiOx) coating on the inner surface of PET bottles, in terms of the ability to reduce the migration of post-consumer compounds from the PET bottle wall into food simulants (3% acetic acid and 10% ethanol), was investigated. The barrier effect was examined by artificially introducing model substances (surrogates) into the PET bottle wall to represent a worst-case scenario. Test bottles with three different spiking levels up to approximately 1000 mg kg(-1) per surrogate were blown and coated on the inner surface. The SiOx-coated bottles and the non-coated reference bottles were filled with food simulants. From the specific migration of the surrogates with different bottles wall concentrations, the maximum surrogate concentrations in the bottle wall corresponding to migration of 10 microg l(-1) were determined. It was shown that the SiOx coating layer is an efficient barrier to post-consumer compounds. The maximum bottle wall concentrations of the surrogates corresponding to migration of 10 microg l(-1) were in the range of 200 mg kg(-1) for toluene and approximately 900 mg kg(-1) for benzophenone. Consequently, the SiOx coating allows use of conventionally recycled post-consumer PET flakes (without a super-clean recycling process) for packaging aqueous and low alcoholic foodstuffs (under cold-fill conditions) and protects food from migration of unwanted contaminants from post-consumer PET.

Is It Advisable to Store Olive Oil in PET Bottles?

To assess the role of the container material on the quality of olive oil, literature results concerning the analytical definition of the quality of oils stored in PET or glass bottles were critically reviewed. The performance of active and passive barrier PET containers may move towards that of glass bottles. The influence of storage conditions was also considered: the main factors affecting the sensory quality loss upon storage are light and the initial oil oxygen concentration, aside from the bottle material. Further research needs are anticipated since new active and passive barrier bottles indeed deserve further attention.     

Altered Oxygen Permeation Through Packaging Polymers in Contact with Liquids—a Mathematical Model Confirmed in a Dilute Xanthan Gum Solution

The ability of liquids to reduce oxygen permeation through low density polyethylene (LDPE), oriented polypropylene (OPP), polyethylene terepthalate (PET), and polyvinylidene chloride (PVTDC) films was mathematically modeled using a water/xanthan solution as a model medium. For low barrier films (LDPE and OPP), the medium substantially reduced oxygen permeation. In PET, an intermediate barrier, the medium produced a recognizable, but minor reductions in permeation. For the highest barrier (PVDC), the medium's influence on permeation was almost unidentifiable. The effect of the medium's oxygen solubility constant and diffusion coefficient on permeation was also examined. For all films, reduction in permeation became significant only after solubility and diffusion values fell below 40% of water values.

Determination of permeation parameters of experimental PET films coated with SiOx to ethyl acetate, oxygen and water vapour.

The permeation parameters of conventional PET films, films coated with SiOx and SiOx-coated films laminated to LDPE were determined for ethyl acetate using the permeation cell/gas chromatography method. Permeation to O2 and water vapour was also determined to monitor overall changes in the barrier properties of the experimental films. Coating of the PET film was achieved by a 'directed evaporation' method that increased the yield of the coating process from 30-35 to > 70%. It was shown that the SiOx coating increased the film barrier to ethyl acetate by approximately 20-30 times. Permeation values showed low reproducibility, indicating the need for further development and standardization of the 'directed evaporation' web-coating process. The barrier to oxygen and water vapour increased by 20-25 and 12-14 times respectively after coating. The web-coating speed did not seem to influence the barrier properties of the films. Permeation coefficients, diffusion coefficients and solubility coefficients were calculated for all samples.

SiO x layer as functional barrier in polyethylene terephthalate (PET) bottles against potential contaminants from post-consumer recycled PET

The barrier effect of a silicon oxide (SiO _x ) coating on the inner surface of PET bottles, in terms of the ability to reduce the migration of post-consumer compounds from the PET bottle wall into food simulants (3% acetic acid and 10% ethanol), was investigated. The barrier effect was examined by artificially introducing model substances (surrogates) into the PET bottle wall to represent a worst-case scenario. Test bottles with three different spiking levels up to ～1000 mg kg^?1 per surrogate were blown and coated on the inner surface. The SiO _x -coated bottles and the non-coated reference bottles were filled with food simulants. From the specific migration of the surrogates with different bottles wall concentrations, the maximum surrogate concentrations in the bottle wall corresponding to migration of 10 µg l^?1 were determined. It was shown that the SiO _x coating layer is an efficient barrier to post-consumer compounds. The maximum bottle wall concentrations of the surrogates corresponding to migration of 10 µg l^?1 were in the range of 200 mg kg^?1 for toluene and ～900 mg kg^?1 for benzophenone. Consequently, the SiO _x coating allows use of conventionally recycled post-consumer PET flakes (without a super-clean recycling process) for packaging aqueous and low alcoholic foodstuffs (under cold-fill conditions) and protects food from migration of unwanted contaminants from post-consumer PET.     

Study of barrier properties and chemical resistance of recycled PET coated with amorphous carbon through a plasma enhanced chemical vapour deposition (PECVD) process

Many studies have been carried out in order to make bottle-to-bottle recycling feasible. The problem is that residual contaminants in recycled plastic intended for food packaging could be a risk to public health. One option is to use a layer of virgin material, named functional barrier, which prevents the contaminants migration process. This paper shows the feasibility of using polyethylene terephthalate (PET) recycled for food packaging employing a functional barrier made from hydrogen amorphous carbon film deposited by Plasma Enhanced Chemical Vapour Deposition (PECVD) process. PET samples were deliberately contaminated with a series of surrogates using a FDA protocol. After that, PET samples were coated with approximately 600 and 1200 Angstrons thickness of amorphous carbon film. Then, the migration tests using as food simulants: water, 10% ethanol, 3% acetic acid, and isooctane were applied to the sample in order to check the chemical resistance of the new coated material. After the tests, the liquid extracts were analysed using a solid-phase microextraction device (SPME) coupled to GC-MS.
