Wide-Mouth Food Jar & Can ISBM Blow Molding Machine

Neck Diameters from 68 mm to 168 mm in One Platform

Standard blow molding machines cap out at narrow-neck bottles (28–38 mm). This series is purpose-engineered for wide-mouth food containers — the mold stations accommodate neck openings up to 168 mm (HGA.ES-2C260 and HGA.FS-1CG220), which covers standard 70-400, 83-400, and 110-400 food jar closures as well as the large-diameter lug-cap formats used on bulk condiment and supplement containers.

No Seam Line — Critical for Hot-Fill and Pressure-Seal Lids

Extrusion blow molded jars have a visible parting seam running vertically down the body. ISBM jars have no such seam because the preform is injection-molded concentrically and blown symmetrically. For products sealed with vacuum lids (pickles, jams, baby food) this matters: a seam line creates a pressure differential point that can compromise the hermetic seal during hot-fill and pasteurization cycles.

Metal-Look PET Can Capability

The series can produce cylindrical PET cans with straight vertical sidewalls and embossed bead patterns that visually replicate tin can aesthetics — a growing format in premium snack, coffee, and protein powder packaging. The straight-wall geometry requires tighter preform temperature uniformity, which the ISBM single-stage thermal control handles more reliably than a reheated two-stage process where preform temperature gradients can cause wall-thinning on the shoulder.

15-Litre Bulk Container Production on ES-2C260

The HGA.ES-2C260 is the largest-volume model in the series, handling containers up to 15,000 ml with a 168 mm neck — that puts 5-gallon water-dispenser jars, large protein supplement containers, and bulk pickle jars within range. At 900 bph on a 2-cavity setup, this targets specialty and mid-volume food producers rather than high-speed commodity lines, where the economics justify a premium, seamless, optically clear container over an extrusion-blown alternative.

4-Cavity High-Output for Medium-Volume Food Jar Lines

The HGA.ES-4C100 and ES-4C130 deliver 3,200–4,600 bph on containers up to 1,500 ml — these are the production workhorses for peanut butter jar blow molding machine applications, honey jar lines, and dry-food canister production where volumes justify the 4-cavity tooling investment but maximum container size stays under 1.5 litres. At 62.5–68 kW installed power, the per-jar energy cost is competitive with two-stage lines at comparable throughput.

Closed Single-Stage Process — No Preform Handling or Storage

For food-contact packaging, the ISBM closed-process advantage is straightforward: PET granules go in, finished food-grade jars come out, with no intermediate preform storage where environmental contamination could occur. This simplifies compliance with FDA 21 CFR 177.1630 (PET food contact), EU 10/2011 migration regulations, and BRC/IFS food packaging supplier audits — auditors can trace the full production chain within a single machine perimeter.

Can this machine produce both a food jar and a standard beverage bottle on the same platform?

Yes — with mold changes. The ES-4C series models can switch between wide-mouth jar tooling and narrower-neck bottle molds provided the neck diameter is within the machine’s rated range. Practically speaking, if you need to run both 1-litre honey jars (98 mm neck) and 500 ml beverage bottles (28 mm neck) on the same machine, you’d need separate injection and blow mold sets for each, but the machine platform handles both. Changeover time on a 4-cavity model runs 4–6 hours with pre-staged tooling.

Is PET the right material for hot-fill food products like jams and sauces?

Standard PET softens at around 70–74 °C, so it’s not suitable for high-temperature hot-fill (85–95 °C) without heat-setting treatment. For hot-fill food jars, you have two options: (1) use heat-set PET (HSPET) with a modified crystallization step, which requires specific mold temperature control that we can configure; or (2) switch to PP (polypropylene), which is rated to 120 °C and handles retort-level temperatures. Both options are available on this machine series. Cold-fill and ambient-fill products — peanut butter, honey, dry goods — run standard PET without modification.

What’s the minimum order quantity for custom food jar molds?

There’s no minimum production quantity for mold orders — we supply a complete mold set (injection mold + blow mold) for any volume. What changes with volume is the economics: for high-volume production runs over 2 million jars per year, the tooling cost is recovered quickly. For low-volume specialty producers (under 500,000 units per year), we recommend starting with a 1- or 2-cavity mold set on the ES-1C130 or ES-2C130 to keep tooling investment proportionate. Custom molds take 35–50 days from drawing approval to first samples.

How do PET food jars compare to glass jars in terms of weight, cost, and consumer acceptance?

A 500 ml glass jam jar weighs approximately 200–250 g empty; a PET equivalent weighs 25–35 g — roughly 85% lighter. That weight difference directly reduces shipping cost and breakage loss in transit. On clarity, PET achieves >90% light transmission, which is visually comparable to glass for most retail formats. Consumer acceptance for PET jars has grown significantly in food categories where glass historically dominated — peanut butter, honey, and dry goods — particularly in export markets where breakage risk during long-haul shipping makes glass economically impractical. The main limitation remains hot-fill suitability, as noted above.

What does “metal-look” PET can mean, and how is it achieved on this machine?

A metal-look PET can is a plastic container with a cylindrical, straight-walled profile and embossed surface features (horizontal beads, stepped shoulders, or base ring) that mimic the visual appearance of a tin can. The effect is achieved through mold design — the blow mold cavity includes the bead and shoulder geometry — combined with downstream labelling or in-mold labelling (IML) processes that apply metallic or printed sleeves. The ISBM process is better suited to this format than extrusion blow molding because the seamless body and uniform wall thickness give a cleaner cylindrical geometry that holds embossed detail more precisely.
