\n

Manufacturing wide-mouth containers for viscous food products like peanut butter presents unique packaging challenges. The jar must be exceptionally strong to prevent denting during filling and transport, offer crystal-clear transparency to showcase the product, and feature a flawless neck finish to ensure a hermetic seal. To conquer these challenges, food packaging manufacturers turn to Ever Power’s advanced one-step blow molding machine<\/strong>. By combining the entire production sequence into a single, continuous operation, we deliver the precision, strength, and efficiency required for premium wide-mouth jars.<\/p>\n

What is One-Step Injection Stretch Blow Molding (ISBM)?<\/h2>\n

One-step ISBM is an incredibly efficient plastics forming technology designed for high-precision hollow containers. It is widely applied across food, beverage, and cosmetics sectors for producing items like PET jars, water bottles, and Tritan sports cups. The core innovation is that the three critical phases\u2014Injection, Stretch, and Blow Molding\u2014are executed sequentially within one integrated machine frame. This completely eliminates the need to cool, eject, store, and secondarily reheat preforms, resulting in immense energy savings, zero surface scratching, and superior dimensional stability for wide-mouth designs.<\/p>\n<\/div>\n

The Streamlined Process Flow<\/h2>\n
\n
1. Injection<\/strong><\/p>\n

Molten plastic forms the preform, rigidly defining the wide-mouth threaded neck to exact tolerances for secure capping.<\/p>\n<\/div>\n

2. Heat Equalization<\/strong><\/p>\n

Latent heat from the injection phase is preserved and perfectly distributed to condition the preform for uniform expansion.<\/p>\n<\/div>\n

3. Stretch Blow Moulding<\/strong><\/p>\n

Biaxial stretching provides the jar with maximum drop-impact resistance and vital oxygen barrier properties.<\/p>\n<\/div>\n

4. Ejection<\/strong><\/p>\n

The defect-free peanut butter jar is automatically ejected onto the conveyor, ready for labeling and filling.<\/p>\n<\/div>\n<\/div>\n
