PBT is a member of the polyester family of plastic fibers. PBT has a matte finish, differentiating it from other more shiny polyester materials. Although it is stretchy, it has less stretch than some other polyesters like Lycra, making PBT a stiffer alternative. PBT has a light and smooth feel, and the material slides smoothly through water, making it great for athletic wear. Among the fibers used to make clothing, PBT has many features that make it stand out as an attractive option for constructing garments. PBT is an extremely strong fiber that can both endure and recover from stretch.

PBT is resistant to humidity and perspiration, allowing it to dry quickly if it gets wet while being worn. The color in PBT fibers can withstand ultraviolet light, so the color of the material will not easily fade after being worn outdoors. The fiber is tough and rigid in durability, yet also soft and flexible so that it can be molded easily. The fiber naturally resists a wide range of chemical, solvents, greases and oils, including the chlorine in chlorinated pool water.

Finally, PBT is snag-resistant and comfortable. All of these properties combined make PBT an ideal fiber for constructing a wide range of athletic garments that can be worn for a variety of indoor and outdoor activities. Nowadays, there are various types of foods such as vegetables, fruits, dairy products, bakery products, legumes, fish, and meat products. Also, there are soups and. Nowadays there are different choices among people. Their choices differ according to various reasons. When considering meat, there are various meat types such as chicken,. Nowadays people eat different types of meat according to their choices.

Lamb, pork, beef, and chicken are some common examples. There are various reasons such. Skip to content What are the advantages and disadvantages of food packaging materials? Those are, Protection — Protect food from deterioration or spoilage due to physical, chemical, or biological damage Communication — Information or any special instructions Convenience — Ease of access, product visibility, handling, and disposal Containment — Hold the content and keep them secure until use The quality of packaged food is directly related to the attributes of food and packaging materials.

Those are, Migration of volatile and non-volatile compounds from packaging materials to the food. This means diffusion. Sorption of components from the food or from the environment into the packaging material. This depends upon the type of interface between the food and the packaging. As an example, the sorption of fatty matter, pigments, and vitamins into the packaging. Permeation of volatile compounds from the food through the packaging. Examples are flavors and water vapor. Primary packaging This is the level that the packaging is in direct contact with the product. Secondary packaging This is another level of protection that commonly use for protection, bundling, and marketing purposes. Tertiary packaging Tertiary packaging facilitates the protection, handling, and transportation of a series of sales units or secondary packaging in order to group everything into unit loads during transit.

Types of packaging materials The major categories of materials used for the packaging of food are glass, metals, paper and paperboard, and plastics. Glass Glass is the most reliable and least toxic material for packaging foods and drinks. Plastic These are the most common and most wide-ranging materials used for food packaging. Synthesized by polymerization of ethylene.

Also, easy to process, and easy to form. Polypropylene It is harder, denser, and more transparent than polyethylene. Has good resistance to chemicals and is effective at barring water vapor. The various forms of polypropylene have different melting points and hardnesses. Popular uses include yogurt containers and margarine tubs. Polyethylene terephthalate This is a thermoplastic polyester that synthesizes by the condensation of terephthalic acid and ethylene glycol.

Instead of injecting the molten plastic, the process uses compressed air to blow the material into the mould. Sam, M. Nuradibah, H. Ismail, N. Noriman, S. Low density polyethylene LDPE and high density polyethylene HDPE are differentiated according to the degree of branching in their molecular structure, giving rise to the varying properties and applications.
