After the International Food Packaging Association recently released the National Survey Report on the Quality of Disposable Paper Tableware, the safety of double-layered food packaging paper products such as instant noodle packaging has attracted great attention from consumers. Is instant noodle packaging safe? Can the outer layer be produced from recycled paper? Is it safe to use food grade base paper only in the inner layer? All this should start with the structure of instant noodle packaging, let us uncover the secret of instant noodle packaging.
The main structure of instant noodle packaging is generally 6 layers, from inside to outside as follows:
Layered structure of instant noodle bowl 1. Inner plastic film, generally made of polyethylene (PE)
The innermost plastic film of instant noodle bowl
100cm2 instant noodle bowl outer gray cardboard is gray under natural light
100cm2 instant noodle bowl outer gray cardboard is bright blue under the illumination of three-use UV analyzer
The outermost plastic film of the instant noodle bowl
In the outermost layer of the instant noodle bowl, there is usually a plastic film. The batch number and production date of the product are generally applied to the plastic film. This plastic film mainly serves to protect the product packaging. In line with food grade requirements, there are no regulations in the national standards. For paper cups, paper bowls or plastic cups, plastic bowls and Other food contact packaging materials, the AQSIQ strictly requires all materials and additives in the audit before the production license (QS) is issued, including the outer bag must be It is food grade.
The above is the main layered structure of the instant noodle bowl. Many consumers have the habit of drinking soup when eating noodles. The outer layer of the bowl is in direct contact with the human hand and mouth. It is difficult to ensure that harmful substances will not invade the health of consumers. The instant noodle bowl is an overall national standard. It is clearly stated in the GB/T 27591-2011 "Paper Bowl" which was implemented on June 1, 2012. "Recycling raw materials should not be used."
The gray cardboard layer, the printed layer, the varnish layer and the outermost plastic film of the instant noodle bowl should be defined by relevant standards and should not be different from inside or outside. The implementation of GB 11680-1989 “Standards for Raw Paper for Food Packaging†in the inner layer of instant noodle bowl does not mean that the whole bowl is safe. It should have its corresponding hygienic standard for molded products. The hygiene standard for raw paper for food packaging is used as the standard for the implementation of bowls. It is not scientific.
In the case that the national standards are still not perfect, any raw and auxiliary materials and chemical substances used by enterprises in the production of food and food packaging materials should have a scientific basis. The basis for not being recognized is violations or even illegal.
It is hoped that the layers of the instant noodle bowl will be revealed, which will cause the production enterprises, industry organizations, testing departments, standards authorities, quality supervision departments and consumers to attach great importance to them, improve standards, plug loopholes, and allow enterprises to comply with regulations. Consumers are assured of consumption!
