The commonly used packaging materials are mainly based on flexible materials such as paper, plastic film, metal foil, etc., which are processed to obtain composite food packaging. The materials used in food packaging are in direct contact with food. First, to ensure food safety and not be contaminated by the outside world; second, to improve the quality of food, good packaging can also extend the shelf life of food. If the packaging material contains substances that are harmful to human body, it will migrate into food, so it is very important to ensure the safety of packaging materials to human body.
The European region attaches great importance to environmental protection and safety and health, and has formulated strict laws and regulations in the field of food packaging. Customers of food and packaging materials exported to Europe often ask ink manufacturers to control the mineral oil content in ink. This requirement is mainly from the European Food Safety Authority EFSA and the German Federal Institute for Risk Assessment BFR, which stipulates that food packaging materials cannot contain VOC, APEO, mineral oil, etc. If the food contains mineral oil (especially aromatic hydrocarbons), long-term consumption will There is a risk of cancer in humans.
According to relevant German regulations, when recycled cardboard is used for food packaging, the mineral oil content in the cardboard should be less than 30ppm, and the migration value in food should be less than 2.5ppm. The main source of mineral oil in recycled paper is to use mineral oil as dilution However, with the introduction of regulations in various European countries, the control of mineral oil content has been extended to various food packaging fields.
There is no global consensus on the harm of mineral oil in food, and the International Codex Alimentarius allows it to be used as a food additive (also known as liquid paraffin/white oil). European and American countries allow it to be used in cocoa, chocolate, confectionary products, baked goods, rice, etc. China’s national standard GB2760 allows it to be used as a coating agent for candies and eggs, and can also be used as a defoaming agent, mold release agent, anti-sticking agent and lubricant in food processing, with no limit. In 2017, when a global brand of chocolate was exposed by the European Union that the mineral oil exceeded the standard, some people analyzed that eating 12,000 chocolates a day may cause certain harm to the human body if the mineral oil ingested.
In addition, the human body ingests mineral oil, and cosmetics may be the first major factor. Because mineral oil is inert, highly reactive, hypoallergenic, and has good sealing properties, it has the effect of blocking the evaporation of water from the skin and is used for moisturizing and locking water. , michelman oleamide emulsion dispersion, resulting in a smooth skin surface. Widely used in hair cream, hair oil, lip balm, lipstick, face oil, skin care oil, sunscreen oil, baby oil, vanishing cream and other products.
Although there is insufficient consensus on the harmfulness of mineral oil, and food packaging is not the main way for humans to ingest mineral oil, European regulatory agencies are still committed to the use of recycled paper for food packaging, and to promote social progress and development.
Before food packaging materials are used, a water-based coating will be made on their surface. Therefore, the environmental protection and safety of the materials used for the coating determine whether the food packaging meets the European BFR standard. Waxes and mineral oils are homogenous and are included in the field of investigation.
In order to better serve paper and board printing ink customers, Nanjing Tianshi has launched PEW-2019, a water-based wax dispersion free of mineral oil and APEO, which can be used for water-based flexo inks that meet European standards. In order to ensure that the ink can meet the European standard, the mineral oil type defoamer cannot be added at all. Every raw material used in Tianshi water-based wax dispersion PEW-2019 is an environmentally friendly raw material that meets the European BFR standard. Not only that, PEW-2019 also has excellent physical and chemical properties: such as excellent abrasion resistance, excellent scratch resistance, good alcohol resistance, storage stability, etc.
