Current situation and development trend of health

The current situation and development trend of health food packaging in China

in recent years, China's pharmaceutical industry has developed rapidly, and the annual GDP of pharmaceutical packaging materials is expected to quickly exceed 20billion yuan in the short term. The current packaging materials for health food in China are very close to drugs. In recent years, with the continuous renovation of health food patterns, the corresponding packaging materials are also developing

a considerable part of health food in liquid form adopts glass packaging. The problem in packaging is not only the glass material, but also the rubber gasket between the bottle body and the bottle cap. Is there a safety problem with this rubber gasket

the state has clear hygienic standards for rubber used in food packaging. Routine test items mainly include whether the content of heavy metals, such as lead and zinc, exceeds the standard; Potassium permanganate consumption, to measure the content of soluble organic matter; Evaporation residue is mainly used to determine whether inorganic substances and alcohol soluble substances will dissolve out when the components of the package contents are different. Judging from the current routine testing, there is not much problem

for glass packaging materials, glass materials used for food packaging have a good development prospect, mainly in terms of the safety of glass. Due to the high chemical stability of glass, from a microscopic point of view, the range and growth rate of extreme output value are among the top in the country, with few dissolved substances. At present, only the United States, Japan and China have formulated corresponding standards for the limitation of arsenic dissolution. The detection indicators are mainly the restrictions on heavy metals, such as lead, arsenic, etc

from the general trend, the requirements of health food for plastic packaging are more rational, and se is developing from appearance to functionality, that is to say, it pays more attention to how to protect the internal quality of products, such as transparency, oxidation resistance and fragrance retention. At the same time, these requirements also ensure the safety of products to a certain extent

however, at the same time, some unsafe factors have also appeared in plastic packaging to ensure its service life Some health food manufacturers emphasize low cost for the packaging of their products. Therefore, in order to meet this demand, some small and medium-sized packaging enterprises use non-standard industrial grade materials instead of the food grade materials required by the regulations. The person in charge revealed that the appearance of the package made of this non-standard material is not much different from that made of food grade materials, and the harm to human health cannot be seen in a short time. However, over time, the hazards of industrial grade materials will be exposed

the continuous technological innovation of health food packaging materials ensures that most of them are solid products. This requires that the plastic packaging directly in contact with the contents should have many functions, such as transparency, safety and fragrance retention. On the basis of the original PV Guangya aluminum will focus on building a one-stop aluminum utilization solution c material from the whole chain of order, design, production, storage, logistics and service, they are using a composite material, that is, PVDC and PVC are used to make functional materials that are more rapid, accurate and low detection. This is to make use of the advantages of good barrier property of PVDC materials and good processability of PVC materials

from the perspective of the development trend of glass packaging materials, food grade packaging is developing towards borosilicate glass. The main component is silicon dioxide, accounting for 70%-80%, the rest is potassium, calcium, sodium, magnesium, etc., and aluminum accounts for very little. The main characteristics of this material are good chemical stability, transparency, fragrance retention and other aspects are also dominant

although plastic packaging has many conveniences, there are also some problems. The problems faced by polymer materials are mainly in environmental protection, one is pollution, the other is difficult to recycle. From the perspective of safety, packaging materials must reach the environmental protection level. Degradable materials can be used for treatment by photodegradation. Although the current general PVC materials are not listed in the environmental protection level, they are not limited internationally. To meet the environmental protection requirements, post-treatment can be used to solve them. After treatment, the raw materials are incinerated. When the temperature reaches 1400 ℃, the harmful substances and pollution can be greatly reduced

there are also ways to solve the recycling problem. The blister plastic products used for drug packaging can be reused in some industrial products after recycling

for glass packaging materials, the main problem is that many glasses use arsenic and antimony as clarifiers, which needs to be improved. In addition, in order to increase the gloss of glass packaging materials, some enterprises deliberately add lead, laying a potential safety hazard

from the perspective of the overall development trend, although the health food packaging materials have different shapes, the development of square is moving towards environmental protection, pollution-free and recyclable
