Paper Valve Bags Sourcing inquiry brief

Write one paper valve bags line that factories can price the same way. Paper Valve Bags Sourcing is an independent sourcing partner. Site configuration lists no street, switchboard or social handle, so this page does not invent a walk-in converting floor, a mapped pin or a published discount percentage. The compact dialog on other pages is only a short copy of the same fields.

  1. Named construction

    Name pasted internal valve or external valve before you name a catalog nickname. Record finished width, length and bottom in mm, plus valve width for the filler spout. Kraft grade and basis weight in gsm or lb belong on the same ply stack: virgin kraft, bleached kraft or recycled kraft. A PE inner ply or PE-coated ply is a separate moisture object; uncoated kraft is not a wet-retort or barrier pack. Water vapor transmission rate is a factory file for that ply, not a number this desk invents. Burst strength at the pasted valve stays a plant test question.

  2. Quantity and unit

    State pieces, cartons or kg against that named construction. A 5,000-piece first drop and a 25,000-piece reprint are different quote objects if a flexographic plate already exists. ISO ICS 55.020 packaging vocabulary treats piece, carton and roll as different units; mixing them in one cell hides converting time. Plate, die-line and sample freight stay outside the piece price unless a factory writes them on the same reply. If two SKUs share a logo but differ in PE inner ply or valve width, keep two quantity rows.

  3. Destination

    Give the receiving US state or postal code and a requested delivery window. Freight, pallet pattern and Incoterm stay outside the piece price unless you ask every factory to include them. A destination written only as “USA” cannot split landed cost from converting cost. Cement custom-size work also needs intended fill mass and whether the bag must match an existing filler spout. Deaeration perforation, if required, belongs on the same construction line because it changes dusting and fill time.

No published street, phone or discount percentage. Follow-up uses the work email you enter after the brief is received. We do not advertise a reply clock because no service-level timer is configured. Artwork, die lines and material files can be requested once the inquiry is open; this form has no upload field.

Fields that keep factory replies on one basis

Pick one paper story and keep it on every line. Mixing a two-ply uncoated 70 g/m² sack with a three-ply 80/80/70 g/m² stack that adds a PE inner ply hides both converting time and recyclability reporting. Post-consumer recycled content can change tear and burst strength; ask the mill sheet for that lot instead of assuming a recycled ply matches a virgin ply at the same gsm. Food-contact or ink-migration testing files, if needed, bind to the named paper and ink lot. They are supplier evidence, not a site-wide badge.

Decoration is a second split. A short, frequently revised logo list can justify digital print so plate charges do not dominate the first drop. A repeating mark near twenty-five thousand pieces more often keeps spot-color control under flexographic printing. That trade-off is a buying choice, not a factory grade. Write whether a die line already exists, and whether valve width is already locked to a filler spout.

Optional target budget should name currency and whether the figure is per piece or for the whole order. High-end, mid-range, budget or undecided describes paper grade, valve construction, print registration and document pack, not a verified factory rating. You do not need an existing quotation to submit. Public Packhelp quote pages recorded 2026-09-15 remain a brief-first process note, not this desk's converting roster. Ahrefs US matching-term labels dated 2026-09-20 inform page intent only.

Send the procurement requirement

Desktop fields sit in two columns: name with work email, then company with phone. The procurement requirement stays full width. Name, work email and the requirement field are the names the endpoint already accepts. Auxiliary product, budget and preference controls, when visible, merge into that same requirement field at submit. They are not extra backend names. Repeating submit or using the browser back button should not keep an old helper summary in the visible requirement text. If JavaScript is disabled, write budget and preference into the textarea. Sending the form opens a written brief, not a purchase order.

Write format, material, size, valve type and print; quantity with unit (pieces, cartons, rolls or kg); destination state or postal code and requested delivery / lead time; required product documents and sample needs. Optional target budget with currency and unit or whole-order basis; optional supplier preference. Artwork files can be sent after we reply; this form has no upload field.
