Polypropylene (PP) is a thermoplastic polymer resin. It is used in commercial and industrial applications. The chemical symbol is C3H6. One of the benefits of using this plastic is that it can be useful in many applications.
1. Benefits of PP film
It does not absorb water like other plastics.
It does not go moldy or deteriorate in the presence of bacteria, mold, or other elements.
Some new types of PP films have an added elastic factor. This gives them a rubber-like composition and this gives them many new uses.
It is not likely to tear so it protects the products inside well, although it is not as strong as other plastics such as polyethylene.
It is lightweight and very flexible.
2. Chemical properties of PP film
Understanding PP film is important because it is significantly different from other types of products. It is also less expensive.
PP film is a great alternative to other alternative materials because it is BPA-free. BPA is not a safe choice for food packaging because it has been shown to leach into food products. It has been linked to various health problems, especially in children.
PP films also have a low level of electrical conductivity. This allows it to be highly effective in electronic products.
Because of these advantages, PP films can be found in almost all types of commodity packaging. This versatile plastic is one of the most commonly used today.
3. Common applications of PP film
Some common applications of PP film include:
Packaging Applications: Good barrier properties, high strength, good surface finish, and low cost make Polypropylene ideal for several packaging applications.
Flexible Packaging: PP films’ excellent optical clarity and low moisture-vapor transmission make them suitable for use in food packaging. Other markets shrink-film overwrap, electronic industry films, graphic arts applications, disposable diaper tabs, and closures, etc. PP Film is available either as Cast Film or bi-axially orientated PP (BOPP).
Rigid Packaging: PP is blow molded to produce crates, bottles, and pots. PP thin-walled containers are commonly used for food packaging.
Consumer Goods: Polypropylene is used in several household products and consumer goods applications including translucent parts, housewares, furniture, appliances, luggage, toys, etc.
Automotive Applications: Due to its low cost, outstanding mechanical properties, and moldability, polypropylene is widely used in automotive parts. Main applications include battery cases and trays, bumpers, fender liners, interior trim, instrumental panels, and door trims. Other key features of automotive applications of PP include the low coefficient of linear thermal expansion and specific gravity, high chemical resistance, and good weather ability, processability, and impact/stiffness balance.
Medical Applications: Polypropylene is used in various medical applications due to its high chemical and bacterial resistance. Also, the medical grade PP exhibits good resistance to steam sterilization. Disposable syringes are the most common medical application of polypropylene. Other applications include medical vials, diagnostic devices, Petri dishes, intravenous bottles, specimen bottles, food trays, pans, pill containers, etc.
Industrial Applications: Polypropylene sheets are widely used in the industrial sector to produce acid and chemical tanks, sheets, pipes, Returnable Transport Packaging (RTP), etc. because of their properties like high tensile strength, resistance to high temperatures, and corrosion resistance.
