manual toothbrush is a hand-held brush made out of hard plastic. The toothbrush has soft plastic bristles for cleaning the gums and between the teeth. Manual toothbrushes are manipulated by the person using them, moving the brush up and down over the teeth and gums to remove plaque, food, and debris.

Tools similar/equivalent to a toothbrush have existed as early as 3500 BC, and have been around since then. The following are their benefits (for modern toothbrushes at least!):Preforms are manufactured from polyethylene terephthalate (PET), so they are called PET preforms. They are produced by RETAL using a highly-accurate injection molding process on equipment from the leading world vendors.

Preform weight depends on the end container’s desired volume. Preforms can be single-layer or multilayer. Barrier preforms provide additional benefits and increased beverage shelf life, thanks to a special layer embedded in several layers of polyethylene terephthalate.

RETAL offers a full assortment of polyethylene terephthalate (PET) preforms for packaging, transporting, and storing drinking water, mineral water, carbonated beverages, juices, nectars, baby food, dairy products, beer, low-alcohol and alcoholic beverages up to 40% abv, edible oil, mayonnaise, ketchup, sauces, household, and cosmetics products

No water waste or expense

Virtually no maintenance or associated ongoing expense

WHAT IS PET?

Polyethylene terephthalate, also called PET, is the name of a type of clear, strong, lightweight, and 100% recyclable plastic. Unlike other types of plastic, PET is not single-use. PET is 100% recyclable, versatile, and made to be remade. That's why America's beverage companies use it to make our beverage bottles. ;

Even the Encyclopedia Britannica notes how unique and valuable PET is - "PET is the most widely recycled plastic. PET bottles and containers are commonly melted down and spun into fibers for fiberfill or carpets. When collected in a suitably pure state, PET can be recycled into its original uses, and methods have been devised for breaking the polymer down into its chemical precursors for resynthesizing it into PET. ;A foldable plastic crate is used for the storage of various goods and for shipping from one location to another. The goods are positioned in a crate, with or without cover, and set or stacked onto a pallet loaded onto a transportation vehicle such as truck or train car and shipped to its destination. Plastic crates provide protection of shipped and stored goods from damage or breakage and simplify the handling of goods.

Presently there are three types of containers used in the market today: wooden crates, cardboard boxes, and plastic crates.

Wooden crates were the traditional tool for storage and handling in the past.

Cardboard boxes were an advanced product used for lightweight goods and are limited in their application.

Plastic crates have been available on the market for about 28 years. In recent years, plastic crates have gained significant market presence and continues to grow.
