Latest Updates products and Insights

In the competitive world of packaging, the demand for durable, user-friendly, and visually appealing wide-mouth jars continues to surge across industries like food, cosmetics, pharmaceuticals, and household chemicals. At the heart of manufacturing these popular containers lies a critical component: the preform mould. Leizhen Mould has established itself as a global leader in designing and manufacturing precision wide-mouth jar preform moulds that set the standard for quality, efficiency, and innovation.

The Critical Role of the Preform Mould in Wide-Mouth Jar Production

A preform is the initial test-tube-like shape that is later blown into its final container form using the stretch blow molding (ISBM) process. The quality of the preform directly dictates the performance, clarity, and structural integrity of the finished jar. For wide-mouth jars, this process presents unique challenges, including ensuring even material distribution and maintaining consistent wall thickness around a larger opening.

Leizhen Mould specializes in overcoming these challenges. Our advanced jar preform moulds are engineered to produce preforms that guarantee:

• Excellent Material Distribution: Prevents thin spots and weak areas in the final jar.

• Superior Clarity and Gloss: Enhances product shelf appeal.

• High-Top Load Strength: Ensures stackability and durability during transportation and storage.

• Leak-Proof Performance: Precision-engineered neck finishes for secure sealing.
