Packaging changes

The complexity of the problems associated with future food packaging can be seen from these examples. We have focused on only one factor in one segment of the food industry—the effect of change in solid waste disposal. The present uncertainties in technical and political aspects of the disposal problem prevent a definite decision as to whether packaging changes should be made. All the industry can do at present is prepare itself for a possible major shift that would have to be made in a short time. 

What is the direction of the mmket (Packaging changes, wholesalers, mass merchants having more voltrme.)... 

Now suppose that a product is stored in a real world situation where the moisture on the inside or the outside of the package changes over time. Then one needs the external environmental conditions and a moisture isotherm for the product. The moisture on the inside of the package may change over time even if the external conditions are constant because the product is reaching equilibrium with the internal moisture content. If the external conditions vary over too wide a range of temperatures, then multiple isotherms may be needed. 

Step 7. The MRC shall also determine whether any other changes are required (such as hazard information, MSDS/label changes, packaging changes). The MRC shall advise the Liaison of any other potential regulatory impacts resulting from the proposed course of action. 

In this chapter, we will examine the types of plastics packaging, their fabrication methods, their occurrence in municipal solid waste, environmental impacts (both positive and negative) associated with their use and disposal, and packaging changes that can reduce those environmental impacts. First, we will examine... 

Non-toxic materials The toxicity status of resins and additives used for food contact and packaging changes frequently, and in many cases percentages and conditions of end use are stipulated. Therefore, we do not attempt to hst such materials here. The current statuses of resins, plasticizers, stabilizers, and other additives with respect to their permissible use in contact with food ( indirect additives ) are spelled out in detail in the Code of Federal Regulations (CFR), Title 21 (Food and Drugs), Parts 173-184. The Code is reprinted annually in book form and updated weekly by the Federal Register, where one should check for the latest word on any particular substance.
