Most chip makers use a multihead weigher on top of a vertical form-fill-seal bagmaker with nitrogen flushing, followed by a seal tester, checkweigher, metal detector or X-ray, case packer and palletiser. Continuous-motion bagmakers and low drop heights help limit breakage.

Frozen fries are weighed by multihead weighers and packed on hygienic VFFS machines in PE-based film that seals well at low temperature, or in paper-based bags in some foodservice ranges. Packs are metal-detected, checkweighed, cased and palletised close to the cold store.

Fresh potatoes are usually packed by a large-bucket multihead or linear weigher feeding a bagger for wicketed, mesh or paper bags, or a VFFS machine for film bags. Sack fillers and box fillers handle 10 to 25 kg packs.

Nitrogen replaces most of the oxygen in the bag, which slows oxidation of the frying oil and helps keep flavour and crunch. The gas also cushions the chips against breakage during transport.

Published indications run from about INR 1.3 lakh for basic Indian-built weigher packers listed online to several hundred thousand dollars for high-speed weighing and bagging systems, and more for complete lines. Buyer indications put new VFFS machines at roughly AUD 20,000 to 250,000 or more in 2026; branded high-speed lines require a quotation.

VFFS machines form bags vertically and fill them with a dropped charge, which suits loose products such as chips and fries. HFFS (flow wrap) machines wrap items or trays horizontally, which suits individual baking potatoes, trays and multipacks.

Accuracy depends on product size and weigher design. For example, Newtec quotes typical giveaway below 0.2% for its 4015B2 weigher on 2 kg portions of products such as potatoes; snack weighers can achieve fractions of a gram on small packs.

Most chip bags use BOPP or metallised BOPP films, often in multilayer laminates for barrier. Brands are moving towards mono-material polypropylene structures and paper-based outer packs to improve recyclability.

Metal detectors find metal only, and cannot inspect through metallised film after sealing. X-ray also detects stone, glass and some plastics and can check fill and seals. Many processors use metal detection in the product stream and add X-ray where customer requirements or risk assessments call for it.

The EU regulates food-contact materials under Regulation 1935/2004 and related rules, and packaging design under the PPWR, applying since August 2026. The US regulates food-contact substances through FDA rules and requires net-quantity labelling. India applies the FSS Packaging Regulations 2018 and the Legal Metrology Packaged Commodities Rules 2011.

Often yes, but mono-material and paper films usually have narrower sealing windows and different stiffness. Machines may need new sealing jaws, temperature control, forming sets or film transport settings, so trials with the new material are essential before switching.
