Emulsion filling, closure selection & consumer access
Six engineering decisions for a 32 oz mayonnaise pack.
BGP-FS-7392 works to the 32 oz Mayo/Economy envelope: 165.1 mm high, 98.4 mm in diameter, 366 g of glass and 964 mL overflow. Its 70-450 deep-skirt finish — historically called 70G — has to be matched to the exact cap. Treating it as an ordinary 70-400 thread is the single most common sourcing error on this jar.
Protect the emulsion during filling
Mayonnaise is a structured oil-in-water emulsion whose apparent viscosity changes under shear. Select a positive-displacement or similarly suitable filler that delivers weight accurately without unnecessary air incorporation or prolonged high shear. Product temperature, nozzle geometry and fill speed should be set from the finished recipe rather than from water trials.
Use the 70 mm mouth for clean access
The wide opening supports spoons, knives and flexible spatulas, which is valuable for a rigid glass pack that cannot be squeezed. Confirm the usable internal bore, shoulder reach and last-portion removal with representative utensils. A cap with an overly deep inner feature can also reduce the available headspace above the product.
Control headspace and shoulder smearing
The jar holds 32.6 fl oz at overflow, leaving only a modest margin above the 32 oz nominal class. Dense emulsions may mound, trap voids or touch the shoulder as the nozzle withdraws. Establish fill weight from density, allow for product leveling and keep the neck land free of oil before capping.
70-450 is a deep-skirt finish
The 70-450, also known as 70G-450, uses a deeper continuous-thread closure than a standard 70-400. Specify cap height, thread engagement and liner construction from the drawing. Metal caps with an appropriate liner and optional vacuum button are common food routes, but the finished process determines whether that indicator has a meaningful role.
Cold-chain condensation affects labels
Refrigerated mayonnaise can develop surface moisture during warehousing, merchandising or consumer use. Choose label stock, ink and adhesive for the real glass temperature and condensation cycle, not only dry application. The 12.37 × 2.91 inch wrap area supports broad communication but should remain clear of the shoulder and heel radii.
Plan the line for a heavy filled jar
A filled unit carries roughly one kilogram of product plus 366 g of glass. Confirm conveyor accumulation, guide-rail contact, capper handling and manual-lift limits with that mass. The cited 12-count pallet contains 1,560 jars, so case strength and pallet deflection matter substantially more than for small condiment packs.
