FSSC 22000-managed production and applicable food-contact documentation are available for project evaluation.

340 ml and 510 ml Wide Mouth PET Jars for Peanut Butter

Huaweier supplies 340 ml and 510 ml clear wide-mouth PET jars for peanut butter packed by ambient or cold-fill processes. The wide opening supports viscous-product filling and consumer spoon access, while the clear body shows product colour and fill level. Because peanut butter density and target headspace vary by formula, the final net weight must be confirmed by filling the customer's actual product into samples. The recommended filling temperature is 40 C or below.

Jar Size, Neck Finish and Closure Details

Packaging Fit for Peanut Butter Packaging

Smooth Peanut Butter Filling

Smooth peanut butter needs a clean filling path and enough mouth access for viscous flow. Evaluate the selected jar with the customer's actual nozzle, fill speed and cap torque before approval.

Crunchy Peanut Butter and Nut Pieces

Crunchy peanut butter contains larger nut pieces, so the opening and filling nozzle must be checked for bridging or product smearing. Do not select capacity from water volume alone.

How to Select the Right Jar and Closure

How to Convert Jar Volume to Peanut Butter Net Weight

Use 340 ml and 510 ml as container-volume references, not guaranteed food net weights. Fill the real recipe, measure headspace and check the finished pack after settling.

How to Select the Cap and Induction Liner

Choose the screw cap together with the jar neck. If an induction liner is required, validate the complete jar, cap, liner and sealing-machine combination rather than approving each part separately.

Filling Sealing and Line Compatibility

 Ambient and Cold Fill Requirement

This PET jar is intended for ambient or cold filling at 40 C or below. If the product leaves processing above this temperature, cool it before filling or select a packaging system designed for the actual thermal process.

Filling Capping and Label Line Checks

Run a line trial for filling accuracy, rim cleanliness, cap torque, liner seal and label placement. The customer performs this validation with its own product and equipment.

Sample Evaluation Before Production

Request both 340 ml and 510 ml samples when the target net weight has not been physically confirmed. Compare fill level, spoon access, label area and packed-case efficiency before selecting the production SKU.

Production Process

OEM and Customization

For this 89 mm neck PET jar, available options may include cap colour, selected printing and outer packing.New jar shapes, neck finishes or special closure structures require separate tooling evaluation.

Sample Evaluation and Customer Line Testing

Huaweier can provide packaging samples for evaluation. The customer should use its own product and its own production equipment to verify actual fill volume and, where applicable, filling, capping, sealing, labeling, conveying and handling performance before confirming the final specification and bulk order.

Frequently Asked Questions About Peanut Butter Packaging

    A:Not without a filling test. Net weight depends on recipe density, air content, fill level and headspace.

Can this PET jar be hot filled?

    A: No hot-fill claim is made. The recommended filling temperature is 40 C or below.

Can an induction seal be added?

    A:It may be evaluated with a compatible cap and liner. Seal strength and peel performance must be tested on the customer's equipment.

What is the regular MOQ?

    A:The regular MOQ is 10,000 pieces. A 5,000-piece trial may be evaluated for a suitable existing mould and standard configuration.
