Plastic packaging materials

Sorted plastic packaging materials are shipped, usually in bales, to processing plants to be converted to polymer resins. The bales are broken and the bottles sorted to ensure that only one type of polymer is further processed. Processing consists of chopping and grinding the bottles into flakes. These flakes are washed. Processing steps such as flotation are used to remove polymeric contaminants from the flakes (15,16). The flakes are melted and converted into pellets. 

It is applicable to plastic packaging materials, where purities with respect to mobile ions, such as Cl and Na, can be checked. In addition, a-particle precursors, such as U and Th, can be determined in solid plastics with sub-ppb detection limits.

The definition of a food additive in Section 201(s) of the Federal Food, Drug, and Cosmetic Act, as amended ( the Act ) refers to substances whose intended use results directly or indirectly in the substance becoming a component of food. The FDA refers to direct food additives as those added to a food to accomplish an intended effect. Indirect additives are those that unintentionally, though predictably, become components of food. Components of plastic packaging materials that can migrate to food are indirect additives.

A tremendous range and variety of chemicals are used to make modem packaging materials. The European inventory list of chemicals used to make plastics intended for food contact numbered more than 1500 listed substances and inventory lists of a similar length exist for chemicals used to make paper, can coatings, inks and adhesives. The chemicals on the plastics inventory list mn literally from A (acetic acid) to X (xylene) with more than 1500 chemicals in between. Substances needed to make effective plastics packaging materials include ...

Until today, the control of transfer from plastics packaging materials into foods has mainly been based on the measurement of the substance(s) in the food or simulant after certain specified, and in most cases standardized, contact conditions. Here, in principal, it can be distinguished between ...

Application Production of polymer-grade terephthalic acid (MTA). MTA is an excellent raw material to produce polyethylene tereph-thalate resin (PET), which is used for engineering plastics, packaging materials—like bottles and other food containers—as well as films. Also, integrated polyester producers use MTA to make various types of fibers.
