boston round glass bottles

Spec Review for boston round glass bottles: lock the open choices that still block a comparable quote, then write what must be verified before an alternative construction is accepted. This page is a packing-specification desk, not a carbon, forest or circular-economy statement.

A quote is comparable only when capacity, neck finish, color, quantity unit and destination sit on one revision. Substituting a different neck family, a different color lot, or a 5 gallon carboy for a boston round is a new brief—not a courtesy swap.

Boston Round Glass Bottle Sourcing uses this page to list buyer-side gaps. We do not claim a factory has already passed a site audit, and we do not treat a directory SKU string as proof of inventory.

Open choices that still block a comparable quote

Capacity and neck finish

Write ml or L and the SPI finish. A 20-400 boston round is not a 28-400 bottle. If only fluid ounces are known, show the conversion on the brief so two factories are not converting differently. Height and diameter, if the filler needs them, belong here rather than in a later email.

Color, wall and decoration

Flint, amber or cobalt changes light protection and sometimes cavity availability. Applied ceramic labeling, pressure-sensitive labels and unprinted bottles are three decoration states. Flexographic printing on a companion label uses a die line and rewind specification that must not be mixed into the glass piece price.

Quantity, pack-out and files

Pieces or cartons by specification. Pallet pattern, divider type and whether a food-contact or migration testing file is required for the intended fill. Post-consumer recycled content, if requested, is a lot file question—not a footer claim.

What to verify before accepting an alternative construction

  • Alternative neck-finish check mark

    Neck family

    A factory that offers a nearby finish must state whether existing closures still fit. Do not accept “similar bottle” language without the finish code.

  • Color lot check mark

    Color lot

    Amber substituted for flint changes UV protection. Cobalt is a different cavity and often a different MOQ. Ask for a color chip or a retain from the quoted melt.

  • Wall weight check mark

    Wall and empty weight

    A lighter wall can change line handling and shipping breakage. If the buyer already has a gram target, put it on the brief so a lighter alternative is visible.

  • Document transfer check mark

    Documents do not travel automatically

    A food-contact or migration testing file for one lot does not cover a substitute composition. Request the file for the quoted alternative before treating it as equivalent.

If the open list is still long, keep the page pending in your own notes rather than forcing one master keyword onto every cell. Then pick an inquiry option or send the locked revision.
