Plastic raw Materials for Bottle handle

Bottle handle plastic raw materials typically include PE, PP, PVC, ABS, and PC, chosen for their strength, flexibility, and durability.

Handles on bottles need to be well designed for striking a perfect balance between looks and functionality.

Moreover, these handles are made from certain plastics that are strong, yet easy to manage and are not prone to damage from the environment.

A well made bottle handle goes a long way in ensuring the right plastic raw materials have been selected.

This article aims to highlight the common plastic raw materials and their respective properties used for making bottle handles.

Common Bottle handle plastic raw materials

• Polyethylene (PE)
• Polypropylene (PP)
• Polyvinyl Chloride (PVC)
• ABS Plastic
• Polycarbonate (PC)

Polyethylene (PE)

Polyethylene is a common choice for handle materials due to their low-temperature flexibility, good impact resistance, and light weight. Moreover, they provide good impact resistance which is ideal for handles on bottles that may be dropped or knocked.

Polypropylene (PP)

Polyvinyl Chloride (PVC)

PVC is valued for its strength and durability attributes, thus is often use where handles are subjected to considerable wear and tear.

 ABS Plastic

ABS (Acrylonitrile-Butadiene-Styrene) is one of the most liked plastic materials due to its impact resistance, strength, and toughness. For handles that are heavily abuse and need to resist deformation, ABS is very suitable.

Polycarbonate (PC)

For transparent plastic handles that need strength, we use polycarbonate due to its strength and clarity. We use PC where high transparency is require, for example, in decorative handles and clear containers.

The Role of Injection Molding in Bottle Handle Production

Most bottle handles are produced through injection molding. This method of plastic processing involves the melting of plastic raw materials and forcing them into a mold of the shape of the handle.

After the mold cools down, the handle is separate. This method is cost effective and yield high production efficiency. It is possible to create handles of complex geometrical shapes.

Core Material Requirements for Injection Molding

The following parameters must be optimize for the injection molding of bottle cap handles to match the material properties:

Flow Control

• PP has better flow than PE and is suitable for complex mold structures (such as multi-cavity molds).
• Adding lubricants (such as stearates) can improve the flow of PE and reduce flash.

Temperature and Pressure Parameters

Key Points:

• PP requires higher injection pressure to overcome melt viscosity.
• PE cools slowly, requiring a longer hold time to prevent sink marks.

Shrinkage Compensation

• PP shrinkage is 1.0-2.5%, while PE shrinks 2-4%. Mold design should allow for expansion.
• Adding glass fiber (PP+GF) can reduce shrinkage to 0.5-1%.
