Inside and outside of the packaging case

[China Packaging Network] The package is bright and beautiful outside, but it is difficult to see because it is difficult to see whether it is riddled with them, regardless of inside and outside, easy to doubt, both inside and outside the repair, packaging good.

Inside and outside milk packaging

Whether it is carton, plastic bag or plastic drum, there is no difference in essence. Because of the carton used to package milk, in order to prevent infiltration, both inside and outside are covered with a plastic film. All three types of packaging, in direct contact with milk, are plastic.

In the eyes of consumers, only the milk packaging is divided into cartons and plastics. It is considered that the cartons are more environmentally friendly than plastics. Therefore, at the time of purchase, the cartons will be loaded with milk even if the price is slightly more expensive. Ma said that this is actually a psychological factor for consumers and a subjective misunderstanding. Of course, if consumers are concerned about the safety of drinking milk, it is not necessary because the quality of milk can be guaranteed as long as the packaging materials are properly handled.

In boxed milk and bagged milk, the choice of milk film becomes very important. Most of the materials used in the film are PE co-extruded films, which must have high barrier to oxygen, otherwise it will affect the shelf life of milk. Suppliers should strictly use food-grade raw materials, environmentally-friendly inks, and strictly enforce the specified standards when testing, so as to ensure the quality of products. At the same time, the choice of ink is another important point, such as benzene-soluble ink, lower cost, the printed pattern is also more beautiful, but now manufacturers are using alcohol-soluble green ink, because benzene-soluble ink contains carcinogens, has been banned by the industry .

Is there risk in eating instant noodles?

The noodles bowl of food safety hidden dangers have long been heard. In recent days, there have been rumors that eating bowls of instant noodles cause serious illnesses. However, according to the professional inspection and evaluation of the quality supervision department, it is not true that the online circulation has been established and consumers can feel comfortable eating.

According to the Shanghai Bureau of Quality Supervision, the wax coating process has been widely used in the production of paper containers. However, due to the low melting point of paraffin, which is around 60 degrees Celsius, waxed paper containers are often used to hold foods with lower temperatures, such as ice cream. Ice water, ice cola and so on. The temperature of the instant noodles is above 90 degrees Celsius, so the waxed paper containers have not been used to make instant noodle bowls. Instant noodle bowls also used to contain polystyrene (PS) foaming materials. However, with the development of production technology, PS foam materials in instant noodle bowls were gradually replaced by polyethylene (PE) plastic film and plastic composite products. The above two risks.

Concerning network rumors, the Shanghai Bureau of Quality Supervision also conducted a safety assessment of 68 batches of polyethylene (PE) paper-plastic composite instant noodle bowls. They were tested to 100 degrees Celsius under conditions of water and oily foods. Whether plasticizers, antioxidants, bisphenol A, or other substances migrate into foods. The evaluation results showed that none of the 68 batches of instant noodle bowls detected the above-mentioned substance migration.

Dairy milk is easy to poison?

Some people have recently said on the Internet that boiled milk with a package can cause aluminum poisoning. Because there is a layer of aluminum foil inside the milk bag, only a thin layer of polyethylene film covers it. During the cooking process, the polyethylene film will be damaged at high temperatures, resulting in the precipitation of aluminum and eventually causing chronic aluminum poisoning. To this end, the relevant person purchased a box of milk to simulate the case of boiled milk. The test was conducted in four ways: no heating, heating for 2 minutes, heating for 10 minutes, and damage to the outer package. Finally with four test samples came to the National Food Safety Supervision and Inspection Center for testing. After inspection by the staff, the results showed that none of the four samples detected excessive aluminum, and the aluminum content was less than 0.1 mg/kg.

Experts from the Chinese Society of Composite Materials explained that the innermost layer of polyethylene film (PE film) in the foil package is not normally boiled at a temperature sufficient to dissolve it and destroy it, so aluminum is not detected. Aluminum is also relatively stable, and it is not a particularly active metal. Therefore, just by simply boiling, it does not chemically enter the food. However, this kind of soft material is also packaged so that we can buy and carry it. It is not used as a heating container. Therefore, when consumers want to drink hot milk, it is recommended to pour it out of the package. In addition, this aluminum foil-wrapped milk must not be heated in a microwave oven. In addition, overheating milk also has an effect on nutrition.
