Plastics are also easy to use because of their light weight. It can be brought anywhere, and at all times. Many home service beauty salons are making use of this benefit, because they can just carry around as many make-up cases and other plastic-made paraphernalia as they can. Plastics also don?t easily break. Most of the outdoor equipment for special events, like picnics or family gatherings is made of plastics. They become great food containers because they don?t easily crumble to pieces. Those more durable plastic-made containers are also easier to handle and carry along.
Everyone knows the significance of plastic packaging. Still, while such knowledge could be useful to companies, few people actually know how plastic containers are made by plastic container manufacturer.
Plastic container suppliers have several methods at their disposal. The most popular of those methods are extrusion blow molding, injection blow molding, stretch blow molding, injection molding, and co-extrusion.
Extrusion blow molding is a way to make high-performance containers with a low weight and cost.
Injection blow molding is performed in three stages. First, melted plastic is injected into a mold to produce a semi-finished product. Compressed air then blows through a core pin to expand the mold. Finally, the container is transferred to a third station for ejection.
Stretch blow molding is used to make stiff containers which are low in weight. Injection molding is used to make wide mouth containers such as plastic jars, tubs, and vials.
Co-extrusion is the newest of plastic bottle blowing technology. It includes sandwiching various plastic resins together with tie layers to produce bottles with barrier and heat-stable qualities suitable for use with hot-filled, hermetically sealed food products. Possible applications include: juices, sauces, jams, toppings, mayonnaise, and pickled products.
Plastic containers such as bulk plastic cups are conveniently in our daily life. And also the automobile spare part is made effective use of to meet our needs.
