Extrusion blow Moulding

Extrusion Blow Moulding (EBM) is a manufacturing process in which plastic is melted at high temperatures and shaped into a hollow tube called a parison. Every parison is then directed into a cold metal mould where air is filled inside it, hence shaping the parison into exactly like it’s mould, for example a shampoo bottle or a container. On adequate cooling, the parison is removed and trimmed. EBM is often used on bottles with built in handles, like jugs & mugs.

Extrusion blow Moulding Overview

The Distinctive Attributes Of Extrusion Blow Moulding

Bottles & Jars

From personal care to households, hospitals to garages, restaurants to offices, plastic bottles and jars are available in every size, colour and capacity.

Over-The-Counter Health Care

OTC drugs are medicines sold directly to a consumer without a prescription from a healthcare professional. Such medications need to be sterile & affordable which is precisely why they are packed in products made via Extrusion Blow Moulding.

Hygienic Packaging Of Food & Drinks

Extrusion Blow Moulding can ensure the sterility of edibles placed in plastic containers for later consumption.

Industrial & Chemical Packaging

EBM is also required by Automobile and light-vehicle industries, heavy goods, gardening equipment, furnishings, pharmaceuticals etc.

  • EBM’s are mono-layer& multi-layer capable.
  • There are often multiple extruders for multiple bottle layers.


Polyolefins are plastic resins combined from petroleum-based gases. The two principal gases are Ethylene and Propylene: Ethylene is the principal raw material for making Polyethylene and Ethylene Copolymer resins; Propylene is the main ingredient for making Polypropylene and Propylene Copolymer resins. Polyolefin resins can be melted, solidified and melted again.

Polyolefins that can be blow moulded include :-

  • Low Density Polyethylene (LDPE)
  • Linear Low Density Polyethylene (LLDPE)
  • Medium Density Polyethylene (MDPE)
  • High Density Polyethylene (HDPE)
  • Polypropylene and Propylene Copolymers (PP)

Extrusion Processes That Sunrise Plastics Take Advantage Of


Shuttle machines are the most widely-used machinery for the EBM process. They are either single-sided or dual-sided and can be manufactured to produce one to six layer containers for cosmetics, pharmaceuticals, food and chemical applications.

The shuttle motion allows bottles to be blown and cooled on the side, without interfering with the parisons, which are continually extruding from the flow-head. This machine is found in all sizes and configurations.
