Pets are one of our best friends. They love spending time with us, playing with us, loving us; but as well as being our best friends they also require a certain amount of care and attention. In this article, we will discuss some of the things that pet owners need to do to ensure that their pets are healthy, happy, and remain in good condition for as long as possible. When looking after your pet you should consider the following items.
High strength polyethylene, commonly abbreviated as PET, PETP, or the more archaic PETE, is a high-strength synthetic polymer and is commonly used in thermal and chemical packaging materials. Although it has many advantages it is also susceptible to degradation over time due to its molecular weight and surface tension. This means that PET is less likely to be punctured than regular paper or cardboard packages. However, because of the higher molecular weight and higher surface tension, it also means that it can be damaged more easily.
PET bottles and PET containers have been found to be resistant to water, light, heat, chemicals and abrasion, and biodegradation. However, they are not completely impermeable to micro-organisms and can allow the growth of harmful contaminants and toxins. It is important that PET bottles are kept away from food as well as beverages and stored in cool, dry areas. Due to its resistance to degradation PET can be used in a variety of applications including pharmaceuticals, cosmetics, food packaging, water treatment, and beverages. PET can also be used as a filter for air conditioning systems, desiccants, lubricants, tires, roofing tacks, disposable cups, cooking equipment, tires, autopilot, cigarette packets, insecticides, paints, and sealants, cosmetics, and plastic bags.
If PET bottles and PET containers are used as recyclable packaging material they will make good materials for landfills. It is estimated that millions of tons of PET bottles and PET containers end up in the United States landfills every year. Because they are difficult to break, contain large amounts of moisture, breakage increases the risk of leaks and spills which contribute to the contamination of land and water. PET bottles are especially troublesome for recycling, although some companies are trying to find innovative ways to make PET bottle recycling easier. However, in the United States and globally most PET bottles are simply recycled.
The PET bottle industry has also developed a number of different plastics that are suitable as pet lining. Some of these substances are suitable for use as pet dyes. PET is combined with other polymers and acids to produce colorless but strong plastic laminated with ethylene glycol (EPD), a material that is safe to handle and suitable for food packaging. The PET is then woven into cloth-like material that has a smooth, non-wrinkled finish and hot-pressed into pellets. The resulting pellets are then poured into a hopper and used to fill martini glasses. Although this is an efficient means of filling a martini glass, it is not environmentally sound as the resulting pellets must be burned or recycled.
Ethylene glycol is another commonly used chemical in PET. It is generally regarded as safe for ingestion and can be used as a lubricant for soft toys. The Food and Drug Administration (FDA) has determined that there are no health hazards from long-term exposure to ethylene glycol, but the agency warns that pregnant women and children may suffer from severe digestive problems if they consume a lot of the chemical. BPA is an example of a harmful chemical found in many PET bottles, but the level of exposure would be extremely low according to the FDA.
Due to the fact that PET is a very strong polymer the plastic bottles can withstand extreme temperatures. This means that it is possible to manufacture shatterproof PET bottles and use them for pet packaging. As well as being shatterproof PET bottles are also recyclable. As well as being recyclable PET bottles are made from recycled polymer chemicals so the bottles are biodegradable and the chemicals released in recycling are also used to manufacture new products. As well as PET being recyclable the containers themselves can be reused to create more PET for packaging.
So when considering the best options for packaging your pet’s food, you should look for materials that are both resistant to chemicals and safe for humans and pets alike. The two most popular PET bottles and containers are those made from recycled polymers but there are other suitable alternatives such as glass. Glass looks good and can withstand heat and is resistant to bacteria and micro-organisms.
