Custom Closure Options For Food Grade PET Jars

Huaweier supplies food-grade PET packaging for repeat projects by food brands, importers and co-packers.
FSSC 22000-managed production and applicable food-contact documentation are available for project evaluation.

Custom Closure Options for Food Grade PET Jars

The closure controls access, resealing and line performance, so it must be selected with the jar neck and food. Huaweier reviews existing screw caps, the verified 40 mm single flip-top option and compatible liner paths before considering new tooling. Huaweier supplies food-grade PET packaging for ambient or cold filling at 40 C or below and checks existing moulds before proposing new tooling.

Customization Choices for Closure And Sealing-System Selection

Screw Cap or Dispensing Cap

Use screw caps for wide access and simple resealing. Use a dispensing cap only when particle size and dose have been tested.

Liner and Tamper Evidence

Select the liner with the cap, jar and sealing machine. Confirm seal, peel and storage performance as a complete system.

How to Select the Right Packaging Configuration

Project Information Required Before Quotation

The project brief must define the food, target pack, closure, quantity and market before a quotation is treated as final. Reference photos help explain intent but do not replace dimensions or drawings.

Existing Mould First Review

Huaweier compares verified stock or mould-available components first. The recommended route should state what remains standard, what changes and what needs a new mould.

Development Filling and Line Compatibility

Custom PET Jar Development Process

Development follows requirement review, existing-mould comparison, drawing or sample approval, tooling when required, first-part inspection, customer filling and line validation, then mass production.

Manufacturing and Export Responsibilities

Guangzhou Huaweier handles international sales, export coordination and customer documents. Dongguan Dongmeng Industrial Co., Ltd. is the manufacturing entity operating the food-packaging production and quality-control system.

Frequently Asked Questions About Closure And Sealing-System Selection

Can any cap fit a jar with the same diameter?

    A:No. Thread profile, finish height, engagement and sealing surface must match.

 Does an induction liner make the pack airtight?

    A:Do not make an absolute claim. Test seal integrity and shelf-life performance for the actual system.

Can a new dispensing cap be developed?

    A:Yes for evaluation after function, neck, quantity and tooling investment are confirmed.

Can Huaweier set the customer's capping torque?

    A:Huaweier can provide component information. The customer validates the setting on its own capping line.
