QINFENG Custom FIBC manufacturer since 2001

Product

Food-grade FIBC

A bulk bag specified around hygiene — liner, closure, foreign-body control and batch traceability — with the applicable market requirements confirmed per project.

A food-grade FIBC is not a different kind of bag so much as a different set of decisions. The woven body carries the load as usual; what changes is everything that touches the product — the liner, the closure, the way seams and loops are kept away from the fill, and the batch records that let a bag be traced back.

The liner is the primary barrier, so its material, gauge and fit are specified rather than left to habit, and the closure has to suit the way the bag is actually opened at the receiving end. Traceability runs from the specification version and sample reference through to the production batch number.

What we will not do is imply a compliance we cannot evidence. The requirements that apply depend on your market, your product and your own specification; we confirm them per project, and we say in writing at quotation stage which documents we can supply and which we cannot.

Product Summary

A bulk bag built around hygiene rather than around load: liner choice, closure, foreign-body control and batch traceability are the decisions that matter. The requirements that apply are confirmed per market and per project.

Core Construction

The woven body is the same family as a standard FIBC, but the construction decisions move to the parts that touch the product. The liner is the primary barrier, so it is usually a food-contact-intended film, fitted as a loose or form-fitted liner with a closure that keeps the product enclosed from filling to discharge. Seams, loop anchorages and any exposed stitching are arranged so that foreign material cannot fall into the product, and the top closure is designed to be opened only at discharge.

Traceability is built in from the start: a specification version, a sample reference and a production batch number are carried through so that a bag in the field can be traced back to its materials and its inspection records.

Key Benefits

BenefitWhy It Matters
Hygiene decisions are made explicitLiner material, closure and foreign-body control are specified and recorded rather than left to habit.
Traceable from bag to batchSpecification version, sample reference and batch number run through the order, so a bag can be traced back.
Product stays enclosedA sealed liner closure keeps the product enclosed between filling and discharge.
Fits existing filling linesThe body fills and lifts like a standard FIBC, so no new equipment is needed for the bulk of the handling.

Configuration Options

Option GroupAvailable RangeNotes
Size75 x 75 x 110 cm to 100 x 100 x 130 cm (typical)Sized from the fill weight and the product's bulk density.
LinerFood-contact-intended PE film, loose or form-fittedGauge and fit are confirmed against your own product specification.
Liner closureTied, heat-sealed or zip closureThe closure decides how the bag is opened at discharge and how it is resealed if partly used.
TopDuffle top, filling spout with liner accessThe top must let the liner be closed after filling without exposing the product.
BottomFlat bottom, discharge spoutA discharge spout with a controlled opening suits product that must not be spilled.
Lifting loopsFour corner loopsLoop anchorages are arranged away from the liner.
Fabric & coating160-200 g/m2 woven PPThe body carries the load; the liner carries the product.
Printing & packing1-3 colours; baled in a protective outerPacking is arranged so bags are not contaminated in storage before use.

Performance & Range

Typical working range is 500-1,250 kg SWL, set by the body and loops as with any FIBC. What is confirmed separately is the liner and closure: the applicable product-contact requirements, the liner specification and the documents that can be supplied are agreed per market and per project, and are stated in writing on the order.

Validation & Testing

In-house checks cover fabric and liner weight, liner fit on a trial fill, closure integrity, seam records, foreign-body controls during sewing and packing, and batch identification. Documents that a specific market requires are arranged per project and are not assumed.

Limitations

The bag does not by itself make a product compliant anywhere: the requirements that apply depend on the market, the product and the customer's own specification, and they are confirmed per project. Where a market requires documentation we cannot issue, we say so at quotation rather than after the order.

Selection Guidance

Best For
Dry food ingredients and food-contact-intended powders where the buyer needs a controlled liner, a sealed closure and batch traceability.
Consider Alternatives When
The product is not food-contact-intended, or the buyer's specification needs documents and approvals we do not hold — in that case the requirement is confirmed before any order is placed.
Must Confirm Before Quoting
The product-contact requirement and who states it, liner material and gauge, closure method, how the bag is opened at the receiving end, batch identification and the documents required for the destination market.

Batch records, liner specifications and pre-production samples can be shared with a named buyer on request. Certificates and approvals we do not hold are never implied; the documents available are listed per project.

Information Required for Quote

  • Product and its product-contact requirement Required

    What goes in the bag, and who states the contact requirement — your own specification or the destination market.

  • Liner material, gauge and closure Required

    If you already specify these, send them; otherwise we will propose and you confirm on a sample.

  • How the bag is opened at the receiving end Required

    Knife, spout or zip — the closure has to suit the way the bag is actually opened.

  • Documents required for your market Required

    Tell us exactly what you need to file. We will confirm in writing what can be supplied.

  • Storage before use

    How and where empty bags are stored, since that affects packing and protection.
