Release time:2023-11-08
Plastic films may not be visible in your daily life,but they have penetrated a wide range of industries and have become an integral part of packaging and lamination.Today,we're going to take a closer look at seven categories of plastic films and reveal their wide range of applications.
1.PVA-coated high-barrier plastic films.
PVA-coated high-barrier plastic films,based on polyethylene plastics,are breaking into the food industry and showing unlimited potential with their excellent barrier properties.This film with excellent barrier properties has a broad market prospect in today's environmentally conscious world.
2.Bi-directional Polypropylene(BOPP):BOPP film is a transparent film.
BOPP film as a transparent flexible packaging materials,thanks to its excellent mechanical properties,low density,corrosion-resistant,and high quality.
Raw material sources in food packaging has a place.In the future,its broad application prospects herald more possibilities.
3.Low-density polyethylene film(LDPE).
LDPE is the star of low temperature and impact resistance and is widely used in food packaging,geo-engineering and agriculture.It not only adapts to the needs of the packaging field,but also plays an irreplaceable role in civil engineering and agriculture.
4.Polyester Film(PET).
Polyester film,with superior mechanical function,excellent optical function.It is widely used as an external material for food packaging to provide better freshness.However,the complexity and difficulty of the judgment also makes customs supervision a challenge.
5.Nylon Plastic Film.
Nylon film is tough and durable,transparent and glossy,and has excellent mechanical properties.It has a wide range of applications in the packaging field and packaging of agricultural products,providing excellent barrier properties for packaging.
6.Cast Polypropylene Film(CPP).
The fast production speed and ease of extruding films make cast film the material of choice for packaging of textiles,food and daily necessities.Its transparency,uniformity and printability give it a wide range of packaging potential.
7.Aluminized Plastic Films.
Aluminized film combines the properties of metal with the lightness of plastic.It is used to block light,protect against UV radiation and improve the shelf life of the contents.It is moderately priced and widely used in food packaging and pharmaceutical packaging.

Commonly used equipment for film concentration
Common equipment used for membrane concentration includes centrifuges,concentrators and evaporators.Centrifuges are used to separate liquids from solids in a sample by spinning at high speeds.Concentrators are used to remove excess solvent from a solution,usually by evaporation.Evaporators are used to remove solvents from solution by heating them until they evaporate.

What machines are needed to produce plastic film
To produce plastic film,you need a plastic extruder and a calender.The plastic extruder will melt the plastic pellets and force the melted plastic through an opening in the die to create a thin plastic tube.The calender will remove the tube and flatten it into a thin sheet of plastic film.You can buy both machines used on eBay or other industrial auction sites.
