Plastic containers manufacturer offers essentials for the packaging needs of many industries. Cosmetic packaging requires plastic containers for makeup and skincare products. Plastic bottles are required to hold vitamins and other medicines in pharmaceutical packaging. And food and beverage packaging make effective use of plastic containers of all kinds, such as plastic bottle 500ML for water and plastic jars for use as deli containers. Everyone knows the importance of plastic packaging. Although this type of information can be useful to companies, very few people actually know how to make plastic containers.

The advancement of latest technology the plastic bottle manufacturer has invented several methods that are used for producing different kinds of bottles. Extrusion blow moulding, injection moulding and stretch blow moulding are some of the methods that are widely used by thousands of plastic bottle manufacturers to conduct their operations. 

Each of these moulding methods has their own pros and drawbacks that you must need to identify before buying the plastic bottles. Understanding these methods will also help you to make an informed decision while buying plastic bottles 500ML for your regular usage.

1. Extrusion blow moulding is a method of producing high performance containers with low weight and cost. First, a round hollow tube (perdition) is formed by an extruder. The two-part mould cavity closes around the parietal and is punched at one end. Then, compressed air shapes the container, cools it, and the excess plastic is cut off.
   
   
2. Injection blow moulding is done in three steps. First, molten plastic is injected into the mould to create a peristalsis. Compressed air is then blown through the core pin to expand the mould. Finally, the container is transferred to the third station for injection.
   
   
3. Stretch blow moulding is used to make rigid containers that have a low weight. It is often used for plastic containers of carbonated beverages. This involves pulling the parietal asymptotically during blow moulding to guide and align the molecules.
   
   
4. Wide mouth Injection moulding is used to make wide-mouthed containers such as plastic jars, tubs and vials. The material is injected into the cavity where the pressure forces the resin to adapt to the mould body. These plastic containers are made without scrap.
   
   
5. Co-extrusion is the latest in plastic bottle blowing technology. It sandwiches a variety of plastic resins with tie layers to form bottles with a barrier and heat-stable properties suitable for use with hot-filled, hermetically sealed food products. Possible applications include: juices, sauces, jams, toppings, mayonnaise and pickle products.
