Packaging, whether flexible or rigid, can affect people's life daily in many ways. The main goal of packaging is to protect the contents from damage and leaking so that they can be distributed safely from one place to another at some given time. No matter for food distribution, pharmaceutical packaging, cosmetics, home-care materials, and many other essential products in modern life, all need appropriate packaging, and polymers, or plastics very often provide the optimal solution and have been widely used on a daily basis. Whether you use it for research or manufacturing, BOC Sciences can provide a wide variety of polymer and monomer products, as well as tailored synthesis services to support your packaging needs.
As packaging is made, various plastics are commonly used and the properties mentioned above enable many different packaging choices, including size, shape, color, weight, hardness, protection, and so on. A polymer refers to a compound with a very large molecular weight, and the molecules are bonded together by structural units or monomers by covalent bonds, e.g., many synthetic polymer materials used as plastics and resins. Some of the most common polymers used for packaging include:
|Polymer||Characteristics||Application for Packaging|
|Low density polyethylene (LDPE)||Translucent or opaque, quite flexible and tough, good solvent resistance||Plastic wraps, clear plastic bags, trays and general-purpose containers|
|High density polyethylene(HDPE)||Recyclability, high strength-to-density ratio, harder and opaquer than LDPE, good solvent resistance||House wrap, water bottles, bottle crates, blown-film shopping bags with handles, HDPE jerrycans|
|Linear low-density polyethylene (LLDPE)||Unique melt flow properties, higher strength, better toughness and stronger rigidity than LDPE||Film, plastic bags, plastic wrap, stretch wrap|
|Polypropylene (PP)||High chemical stability, good hygienic performance, high heat resistance, non-toxic||Microwave tableware, plastic bucket, thermos shell, woven bag|
|Polystyrene (PS)||High transparency, shiny surface, non-toxic. versatility (can be rigid or foamed), excellent moisture barrier for short shelf-life products||Disposable food containers; meat and poultry containers, and rigid food containers; food service applications: cups, plates, bowls, and cutlery; egg cartons; aspirin bottles|
|Polyvinyl chloride (PVC)||Soluble in organic solvents such as THF and DMSO, good acid and alkali resistance.||Rigid packaging applications: blister packs and clamshells; clear food packaging like plastic wraps, films and bags; medical tubing; shampoo bottles|
|Polyethylene terephthalate (PET)||Good transparency, durability, good chemical stability, non-toxic||Soft drink bottles, medicine bottles, cosmetic bottles, oil bottles and various bottle caps, insulation caps|
|Ethylene vinyl acetate (EVA)||Excellent clarity and gloss with little odor, good water resistance, corrosion resistance, easy processing, thermal insulation, non-toxic||EVA copolymers are used as adhesives in packaging; EVA films or bags to pack rubber additives or wax|
|Ethylene vinyl alcohol (EVOH)||Exceptional gas barrier properties, recyclability and environmentally safe; high resistance to hydrocarbon fuels, mineral oils and many organic solvents||EVOH material is particularly suited for packaging food, drugs, cosmetics, and other perishable products to extend their shelf life; plastic fuel tanks, chemical packaging and agricultural films|
|Polyvinyl alcohol (PVA)||Extreme hydrophilicity, high resistance to hydrocarbons, mineral oils, and many organic solvents, non-toxic||PVA film is a cold and hot water-soluble film for diverse packaging applications including food products, detergents, pharmaceuticals and agricultural chemicals.|
|Polylactic acid (PLA)||Transparent, biodegradability and recyclability, low impact capacity and brittle, Alcohol and water resistant||Disposable tableware i.e., cups for cold beverages, carry-out containers, eating utensils; deli containers; fruit and vegetable trays; packaging for refrigeration and deep freezing|
