PROTECTIVE PACKAGING

Protective packaging is primarily required to prevent moisture pickup. The flavor quaUty of regular instant coffee changes very tittle during storage. However, the powder is hygroscopic and moisture pickup can cause caking and flavor impairment. Moisture content should be kept below 5%.

The fatty tissues in your body are made from lipids. They act like protective packaging around fragile organs, such as the heart. They insulate the body from excessive heat or cold, and they act as padding to reduce impact from collisions. 

Harden s (27) market survey of the growth of polyolefin foams production and sales shows that 114 x 10 kg of PE was used to make PE foam in 2001. The growth rate for the next 6 years was predicted as 5-6% per year, due to recovery in the US economy and to penetration of the automotive sector. In North America, 50% of the demand was for uncrosslinked foam, 24% for crosslinked PE foams, 15% for EPP, 6% for PP foams, 3% for EVA foams and 2% for polyethylene bead (EPE) foam. As protective packaging is the largest PE foam use sector, PE foam competes with a number of other packaging materials. Substitution of bead foam products (EPP, EPE, ARCEL copolymer) by extruded non-crosslinked PE foams, produced by the metallocene process was expected on the grounds of reduced costs. Compared with EPS foams the polyolefin foams have a lower yield stress for a given density. Compared with PU foams, the upper use temperature of polyolefin foams tends to be lower. Eor both these reasons, these foams are likely to coexist.

JSP Corp. is expanding market applications for P-Block, a non-crosslinked PP foam, as an antomotive bumper core material. An ambitions market development plan will be nndertaken this antnmn following fnll-scale start-up of its new plant cnrrently nnder constrnction. P-Block is also being used as protective packaging for computers and other precision machinery. 

These foams have the potential to replace the foams currently used for food and protective packaging. 

The formulation and the container closure system (container, closure, pump, and any protective packaging) collectively constitute the drug product. The design of the container closure system affects the dosing performance of the drug product. 

Inhalation solution and suspension drug products are typically aqueous-based formulations that contain therapeutically active ingredients and can also contain additional excipients. Aqueous-based oral inhalation solutions and suspension must be sterile (21 CFR 200.51). Inhalation solutions and suspensions are intended for delivery to the lungs by oral inhalation for local or systemic effects and are used with a specified nebulizer. Unit-dose presentation is recommended for these drug products to prevent microbial contamination during use. The container closure system for these drug products consists of the container and closure and can include protective packaging such as foil overwrap.

The skin is not just the protective packaging of the body it is a large and complex organ. Indeed it is the largest human organ, with an area of 2 square metres. It can be thin, as eyelids, or thick, as on the soles of the feet. It constantly grows from the inside and is constantly lost from the outside, and we shed around 2 g of dead skin cells per day as dust. The outer layer of the skin is known as the epidermis, below that... 

Before the storage of the flammable liquid (crude sulfate turpentine, CST), there were no flammable materials in the terminals enclosure. Local fire protection agencies specified a fixed foam-piping, fire-suppressing system as a condition to store flammable liquids. The terminal s management agreed to the terms of the protection package. 

In view of the necessity for getting waste disposal under control coupled with the limited fossil raw material resources, biodegradable polymer and in particular polymers from renewable resources will gain importance in the future. In the most sensitive application area, food contact materials and articles, it is possible initially to use these materials in very limited amounts. The easy decomposition of these packaging materials is in opposition with the inertness needed to protect packaged food. These polymers are particularly sensitive to moisture. By finishing operations such as surface treatments, one could improve the inertness of these polymers. However, the degradability would be diminished by such processes.
