PET Packaging for Freeze-Dried Products

Freeze-dried products can look very different in the same nominal jar because shape, porosity and particle size affect how the pieces settle. A wide-mouth jar is useful for irregular pieces and can reduce product damage during manual or automated filling, but the opening size and final headspace still need to be checked with the real food.

Why Food Brands Choose Our PET Jar Packaging

1. Consistent Quality for Repeat Orders

Controlled dimensions, neck finish and molding processes help maintain batch-to-batch consistency for repeat packaging orders.

2. Food Packaging Quality Control

Food-grade virgin material and routine production inspection support stable packaging quality under our FSSC 22000-certified food safety management system.

3. Stable Production Capacity

13 production lines support samples, bulk production and long-term repeat supply for food packaging projects.

Product Specifications

Product Applications

Freeze-Dried Fruit

Whole berries, strawberry slices, mango pieces and similar freeze-dried fruit are often light and irregular. A clear jar helps display the product, while a wider opening makes it easier to fill larger pieces without forcing them through a narrow neck. The selected seal should also reflect the product's moisture sensitivity.

Freeze-Dried Candy

Freeze-dried candy can expand significantly compared with the original confectionery. Capacity should therefore be tested with the finished freeze-dried product, not calculated from the original candy weight. A transparent jar is useful where color and texture are important to the retail presentation.

Freeze-Dried Snack Pieces

Mixed freeze-dried snack pieces may vary in size and density within one formula. Sampling with the final product helps confirm fill level, headspace and whether the jar opening is practical for both production and consumer use.

Packaging Selection Guide

What jar size is suitable for 85g of freeze-dried food?

There is no reliable universal conversion from 85g to a jar capacity. The required volume depends on the product's bulk density, piece size and desired headspace. The safest approach is to test 85g of the finished product in several existing jar samples and select the size that gives the intended shelf appearance and filling efficiency.

When should a larger jar be selected for a lightweight product?

Choose a larger jar when the product fills too close to the neck, when irregular pieces bridge during filling, or when the brand needs visual headspace for a clean retail presentation. The goal is not to maximize empty space, but to match the jar to the real product and packaging process.

Food-Grade Production and Quality Control

Quality checks should focus on material, appearance, jar weight, critical dimensions, neck finish and closure fit according to the approved specification. Link this section to Huaweier's Quality Control page for current FSSC 22000 and applicable food-contact documentation instead of repeating long certification text on every product page.

Production Process

FSSC 22000 & EU Food Contact Compliance

Our food packaging production is managed under an FSSC 22000-certified food safety management system. Relevant EU food-contact test reports are available for applicable materials and products.

OEM and Customization

For suitable existing molds, customization may include cap color, selected printing and packing details. New jar shapes, neck finishes or special closure structures require separate tooling evaluation. Keep decoration customization and new-mold development clearly separated.

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.

3. Q: Do you have experience working with international brands?

    A: Yes. We supply packaging solutions to food brands across Europe, North America, Middle East, and Asia, supporting both trial and long-term repeat supply programs.

4. Q: Can freeze-dried candy be packed in PET jars?

     A: PET jars can be evaluated for dry freeze-dried candy applications where the filling temperature and product requirements are compatible with PET. The final closure and moisture-protection system should be confirmed for the specific product.

5. Q: Can I send my product for a filling test?

    A: Yes. Sending the actual product is the preferred way to confirm capacity, headspace, opening size and presentation before bulk ordering.
