Bottle food-grade

Eastman Chemical is starting a pilot depolymerisation plant that it hopes ean provide a eost-effeetive solution for some new hard-to-reeyele PETP bottles. In the laboratory, the proeess has been able to handle all the different eoloured PETP and all the barrier layers that have been tested. The proeess produees food-grade material.

Several bottle-to-bottle recycling technologies have been developed to convert washed PET flakes to food-grade PET pellets [129,130], They can be categorized by four different ways of processing. The succession of process steps has an influence on the final result. To see the implications, each process option has to be evaluated with respect to the requirements discussed before. Some of these critical aspects are indicated in Table 4.2. 

As we will see in Chapter 9, multilayer blow molding is sometimes used as a way to incorporate recycled polymer in food-grade bottles. For safety reasons the use of recycled plastics in packaging that comes in direct contact... 

Store water in thoroughly washed plastic, fiberglass, or enamel-lined metal containers. Don t use containers that can break, such as glass bottles. Never use a container that has held toxic substances. Sound plastic containers, such as soft drink bottles, are best. You can also purchase food-grade plastic buckets or drums.

Tfie first U.S. approval for use of mecfianically recycled PET in direct contact with food came in 1994, for Johnson Controls (later Amcor s) SuperCycle recycled PET. Amcor cnrrently operates a PET recycling facility in Beaune, France, with a capacity of 15,000 tons per year. About 75 percent of prodnction is food-grade SuperCycle resin, and the rest is nonfood-grade NuCycle. Other companies subsequently also obtained FDA approval. For example, in 1996, WeUman received an FDA letter of nonobjection for their EcoClear resin made from 10 percent recycled PET from postconsumer bottles. ...

Cerrada [97] has examined the gas barrier properties of food-grade ethylene-vinyl alcohol copolymers used in film and bottle manufacturing as a function of the ethylene and vinyl alcohol content. Oxygen transmission rates have been reported for polyolefin nanocomposites [98]. 

In 1999, Phoenix Technologies LP became the first company to receive FDA approval for use of 100 percent curbside recycled PET in food containers. In 2001, the company gained approval for use of this material in hot-filled bottles. Commercial production of food-grade curbside recycled PET began in December, 2000. The process is in use in Australia to make 25 percent recycled-content bottles for Coca-Cola. ... 

PVC compounds are formulated for specific applications with specific requirements thus certain additives are used in some applications and not in others. For example, plasticizers used in roofing membrane may not be acceptable for food wrap film. In some cases, additives are reviewed and approved for applications. US FDA and NSF International review and/ or approve resins and additives for food grade bottle and potable water pipe, respectively. 

Mixed metal stabilizers, such as those used in flexible compounds, have generally not been used for rigids, with the exception of calcium/zinc stabilizers for some food grade bottles and sheet. Recently, more robust calcium/zinc formulations have been developed for rigid extrusion, including for pipe.

FDA-sanctioned octyltin and methyltin stabilizers are also used in food packaging film and sheet, where relatively low levels of plasticizer are added to add flexibihty. With 20-40 phr plasticizer, 1.5-2.0phr such as Mark OTM, Thermohte 890, or others listed above in connection with food-grade bottles can provide brilhant clarity. 

Suitable grades are usable in contact with food and are used for food packaging, milk bottles for example.
