Flexible Food Packaging by Product and Filling Process

Start with the food, filling process and required pack format. XLD will compare the practical rollstock or selected premade routes, then confirm the exact structure, supply route and supporting documents for the quoted SKU.

Start with the Product Condition and Filling Process

Match the packaging route to the food and the line

Dry powder or granule

Resolve moisture/oxygen sensitivity, dust, dose, seal contamination and machine format. Then review Sachet rollstock or stick-pack film.

Liquid or semi-liquid

Resolve chemistry, fill temperature, seal contamination, leak-test method and pack size. Then review Liquid rollstock or a selected premade pouch after project review.

Snack, bar or bakery item

Resolve grease, oxygen/moisture target, pack geometry and flow-wrap line. Then review Wrapper-pack film.

High-protection product

Resolve shelf target, storage, test method, light/oxygen/moisture need and seal window. Then review High-barrier rollstock.

What to Send for a Useful Recommendation

Send the variables that change the route

Food: condition, ingredients/chemistry, fill weight, shelf and storage target.
Process: hot/cold/ambient fill, VFFS/HFFS/flow-wrap or premade filling, line speed and seal conditions.
Pack: dimensions, roll-fed or finished pouch, opening/closure and display need.
Protection: oxygen, moisture, light, grease, aroma or puncture target with any test method.
Commercial: SKUs, quantity, artwork, destination, documents and sample/trial stage.

Our Recommendation Before You Select a Structure

Choose the structure only after the contents, fill temperature, storage target, seal method and machine path are clear. For oxygen-, moisture- or light-sensitive products, define the measurable protection target and test conditions.

If the current pack already runs, send a sample or structure. If it fails, tell us whether the issue is feeding, registration, seal strength, leakage, cracking, odour, migration or shelf-life performance.

Check These Points Before You Order

Use the exact structure, not a category name, for final approval

Confirm the offered structure, supply route, MOQ, timing and available evidence in the quotation. Shelf life, machine fit, food-contact status and end-of-life claims depend on the complete structure and the agreed validation conditions.

Send the Product, Process and Current Pack

Share the food, filling process, pack format, machine/seal conditions, structure or protection target, quantity, market and document needs.
