Format Adaptation Details

Container Format / Closure Spec

Container Format

Wide-mouth glass jars (TO-66 / TO-82) optimized for steam-injection vacuum capping and hot-filling.

Closure Spec

Euro-jar

Adaptation Area

Steam-vacuum capping chambers & jar guides

Critical Dimension

Rim flat area & TO-66/82 screw thread pitch

Engineering Assessment

Engineering Adaptation & Assessment Board

Suitable Sauces

Tomato paste, ketchup, particulate tomato sauce, tomato-ketchup-cold.

Impact on Filler

Requires heavy-duty piston dosing pumps with diving pneumatic nozzles. Pre-heating tunnel required for 85°C hot-fill to prevent thermal shock fracture.

Impact on Capper

Requires steam-injection vacuum capping chambers. Superheated steam is sprayed to purge oxygen and soften the plastisol liner before twisting.

Impact on Labeler

Requires high-volume hot-air blowers or air knives to dry condensation from cold/hot jars completely before applying paper/PP labels.

Required Samples

100 pcs of empty glass jars, 200 pcs of matching twist-off metal lids, and 5L of actual sauce sample for viscosity flow trial.

Packaging Line Risks

Jar rim residue leaks

Sticky food splashes on the rim block twist-off vacuum capping. FPM adjusts nozzle cut-off and suck-back parameters.

Glass transfer shock fractures

Jar friction creates cosmetic micro-cracks on linear paths. FPM designs custom-molded Delrin guide rails.

Vacuum deflection

Vacuum pressure deforms glass structures when cooling rates mismatch. FPM calibrates steam pressure settings.
