Food and beverage applications generated the largest revenue share of the global in-mold label market in 2023 — 41.3%, according to Grand View Research. That single figure explains why food-contact paperwork now settles a growing number of in-mold label sourcing decisions. Once a label is fused into the wall of a yogurt cup, ice cream container or beverage bottle, it stops behaving like an accessory sitting on the surface of packaging. It becomes part of the packaging material that touches food.

For containers sold into the United States, the reference point for olefin-based materials is FDA 21 CFR 177.1520. The ZY-IML-SERIES in-mold label is documented under a food contact test report issued by SGS with the certification number NGBEC2501946006, assessed against that standard for the US market. This reference walks through what the report actually covers, what sits outside its scope, and how a buyer can cross-check it against BRCGS, ISO22000 and QS documentation held in the same supplier file.

Why a Report Number Beats a Certificate Image

Procurement teams rarely reject a supplier because a logo is missing from a marketing page. They reject a supplier because the compliance document cannot be traced. A certificate image without a number, an issuing body, a standard citation and a product scope is not evidence — it is decoration. A report number changes the conversation because it can be matched to a document, a date, a named holder and a described product.

NGBEC2501946006 is that kind of identifier. It belongs to an SGS-issued FDA food contact test report prepared for the ZY-IML Series and assessed against FDA 21 CFR 177.1520 for the US market. Read alongside the series' BRCGS Packaging Materials, ISO22000 and QS compliance statements, it forms a documentation chain that a buyer can inspect line by line rather than trust as a whole.

The practical value of a traceable number appears at three moments: during supplier shortlisting, during a second-source audit, and during a customer's own food-safety review. In each case the question is the same question a customs or QA reviewer would ask — which document, which standard, which product, which holder.

What NGBEC2501946006 Actually Documents

The report is a food contact test report, not a general quality certificate. Three elements define its boundaries.

• Issuing body: SGS, which positions the document as an independent third-party assessment rather than a self-declaration.
• Applicable standard: FDA 21 CFR 177.1520, the section of the US indirect food additive regulations that addresses olefin polymers — the material family that polypropylene and polyethylene belong to.
• Product scope: the ZY-IML Series in-mold label, as described in the report's product identification.

FDA 21 CFR Part 177 regulates polymers used in direct food contact applications, including polyethylene and polypropylene. Because the standard is cited by section, a reviewer can tell immediately which chemistry logic was applied and which material family sits inside the assessment. That is the difference between a document that answers a compliance question and a document that merely signals good intentions.

Series Scope: Why the ZY-IML-SERIES Designation on the Report Matters

The ZY-IML Series is an in-mold label (IML) range produced for the injection molding industry, made primarily from polypropylene (PP) and polyethylene (PE), and available in food grade, daily chemical grade and industrial grade types. Its material options also include PET and multi-layer composite laminates, with food-grade variants using food-grade virgin resin.

A series-level description on a test report is more useful to a multi-SKU buyer than a single-sample test, but it also places a duty on the buyer. Any construction ordered must fall inside the description printed on the report. That means checking the film material, the film type and the grade against the scope wording, rather than assuming that a brand-level approval automatically covers every variant, finish and thickness in the catalogue.

The ZY-IML Series is produced by Zhejiang Zhongyu Science and Technology Co., Ltd. (YZY), a Wenzhou, China-based manufacturer of in-mold labels, sealing films, embossed lidding films and POF films, established in 2009 and operating a 20,000 m² manufacturing facility with approximately 250 staff. Product documentation, including the FDA food contact report, is issued under the legal entity name, which is why the entity line on the report deserves the same attention as the number itself.

Reading the Layer Stack Behind the Certification

A food-contact assessment of an in-mold label is effectively an assessment of a stack: film, resin and ink. In the ZY-IML Series, the material base is PP, PE or PET, with food-grade virgin resin specified for food contact applications and food-grade low-migration water-based ink used for printing. Those two choices — virgin resin and low-migration ink — are the parts of the construction that matter most when a buyer asks why a label is considered suitable for food contact rather than merely printable.

Printing is carried out with 8-color high-precision rotogravure equipment at a maximum printing width of 1200mm, with printing precision of ±0.1mm. Film thickness ranges from 30μm to 100μm and is customizable. Available film types include Complex White Gloss Film, Complex Transparent Gloss Film, Standard Gloss Film, Matte Laminated Film and Holographic Film, with surface finishes in glossy, matte, orange peel, holographic and custom texture.

The mechanical values matter because they determine whether a certified material survives the process it was certified for. Adhesion of at least 5N with no peeling during injection molding, tensile strength of at least 20MPa, 4H pencil-hardness scratch resistance, and tolerance of weak acids, alkalis and common detergents all describe a label that has to behave like part of the container, not like a sticker applied after molding.

How FDA 21 CFR, BRCGS, ISO22000 and QS Divide the Work

Buyers frequently treat food-grade documentation as a single category and then wonder why a supplier presents four different documents. The four answer different questions, and a complete file usually needs several of them.

Regulation (EU) No 10/2011 governs plastic materials intended to come into contact with food in the European Union. A buyer shipping to both the US and the EU therefore needs both frameworks represented in the file, and the ZY-IML Series states migration test compliance with EU 10/2011 alongside the FDA 21 CFR, BRCGS Packaging Materials, ISO22000 and QS compliance statements. Treating any one of these as a stand-in for the others is one of the most common documentation errors in food packaging sourcing.

Application Fit: Where a Food-Grade IML Belongs

The ZY-IML Series is used in food packaging and other industries, with the label serving food contact labelling, branding and identification. The food-grade variants map to containers such as yogurt cups, ice cream containers, bubble tea cups, plastic bottles and plastic containers, where the operating range of −20℃ to 120℃ supports both hot filling and cold chain distribution.

Daily chemical and industrial grades serve the same production process with a different compliance target: shampoo and detergent bottles, cosmetic containers, paint buckets and lubricant buckets. These applications rely on the mechanical and print performance of the label — adhesion, chemical resistance and image durability — rather than on food-contact approval, and the grade distinction on the product description is what keeps that boundary clear.

Market structure supports this split. Food and beverages accounted for the largest revenue share of the in-mold label market in 2023 at over 41.3%, polypropylene held 47.2% of the material share in the same year, and injection molding accounted for more than 57.1% of the production process segment. In other words, the material family that FDA 21 CFR 177.1520 addresses is also the dominant material family in the market, and the process that the ZY-IML Series is built for is the dominant process.

Where the Certification Stops

Every food-contact document has an edge, and the edge is where purchasing mistakes happen. Three boundaries are worth stating plainly.

• It is a material-level document. The report describes the label material within a defined scope. It does not validate the container resin, the molding parameters or the filling conditions used at a converter's plant.
• It is market-specific. FDA 21 CFR 177.1520 addresses the US framework. A European buyer still needs the EU 10/2011 dimension, and a Chinese buyer still needs the QS dimension.
• It is grade-specific. Food grade, daily chemical grade and industrial grade serve different applications, and approval for one grade does not transfer to another.

Because final performance depends on resin grade, mold design, cycle conditions and filling temperatures, buyers typically run their own validation on production tooling before committing to full-scale output. Certification reduces material risk. It does not remove process risk.

How In-Mold Labelling Changes the Documentation Burden

Traditional adhesive labels and shrink sleeves are applied to a container after it is formed. They add a separate material to the outside surface and, in practice, a separate compliance question. An in-mold label is different in kind: the printed film is placed in the mold and bonded into the container wall during injection molding, so the label and the container become one article.

That structural difference is what pushed material-level documentation to the front of the buying process, and it is also the source of a genuine limitation. Because the label is fused into the wall, the container's own resin now sits inside the same food-contact conversation. A certified label cannot compensate for a non-compliant container material or for molding parameters that fall outside the label's processing window. The stronger the integration, the more the buyer's own process becomes part of the compliance story — which is why the adhesion and temperature figures in the specification carry as much weight in a supplier review as the certificate number.

Market Trend: Documentation as a Shortlisting Filter

Published market estimates for in-mold labels diverge, and the divergence is itself informative. Grand View Research values the global market at USD 2.31 billion in 2023 and projects USD 3.14 billion by 2030, while Market Research Future estimates USD 2.72 billion in 2024 with a projected CAGR of 3.94% reaching USD 4.16 billion by 2035. The differences come from segmentation and base-year definitions — the same reason a buyer should date and source every number used in a sourcing decision.

Regionally, Asia Pacific is the fastest-growing and largest regional market for in-mold labels as of 2024, according to Mordor Intelligence. The global in-mold label industry also includes large international players such as CCL Industries, Multi-Color Corporation and Huhtamaki. For a buyer comparing a specialist Chinese converter with a multinational group, the productive comparison is not brand scale but document scope: which standard, which product description, which grade, and whether the report can be traced and re-verified.

The pattern emerging across food packaging procurement is consistent: food-contact documentation has shifted from a closing formality to a shortlisting filter. Supplier files are being read earlier in the process, and a report number that can be checked is increasingly treated as evidence, while an untraceable certificate is treated as a gap.

Future Outlook

Three developments look likely to shape how in-mold label compliance is evaluated over the next buying cycles. First, series-level documentation will matter more than single-sample tests, because buyers managing multiple container formats need scope rather than a snapshot. Second, verification will become routine: report numbers, named holders and cited standard sections will be checked against issuing bodies rather than accepted at face value. Third, documentation quality will separate suppliers more clearly than print samples, because appearance can be matched quickly while a traceable compliance chain cannot.

For the ZY-IML Series, the SGS report NGBEC2501946006 assessed against FDA 21 CFR 177.1520 sits alongside BRCGS Packaging Materials, ISO22000 and QS compliance statements and an EU 10/2011 migration test claim. That combination is what makes the series usable across food, daily chemical and industrial packaging programmes — provided the buyer checks each document against the specific grade, film construction and market in play.

FAQ

What exactly does SGS report NGBEC2501946006 cover?

It is a food contact test report issued by SGS for the ZY-IML Series in-mold label, assessed against FDA 21 CFR 177.1520 for the US market. The number NGBEC2501946006 is the identifier a buyer should look for when requesting documentation. The report addresses food-contact suitability of the label material within the described product scope; it is not a general quality certificate covering a manufacturer's entire catalogue.

Does the report cover every film construction in the series?

The report is tied to the ZY-IML Series designation. Because the series includes PP, PE and PET films, multi-layer composite laminates and several surface finishes, a buyer ordering a specific construction should confirm that it matches the product description in the report rather than assuming that all variants are automatically inside scope.

Which material family does FDA 21 CFR 177.1520 address?

FDA 21 CFR Part 177 regulates polymers used in direct food contact applications, including polyethylene and polypropylene. Section 177.1520 addresses olefin polymers, the family that PP and PE in-mold label films belong to. Buyers working with other material options in the same series should confirm how those materials are covered within their own documentation.

Are BRCGS, ISO22000 and QS the same thing as the FDA report?

No. They address different layers of compliance. BRCGS Packaging Materials covers site-level product safety and quality management; ISO22000 is a food safety management system standard; QS addresses the Chinese domestic market; the SGS FDA report addresses food-contact suitability of the material for the US market. A complete supplier file normally contains several of these because no single document substitutes for the others.

How can a buyer verify report NGBEC2501946006?

Request the full report rather than a cropped image, then check four things: that the report number is NGBEC2501946006, that the issuing body is SGS, that the named certificate holder matches the supplier's legal entity, and that the product scope and the cited standard (FDA 21 CFR 177.1520) match what is being purchased. Where internal policy requires it, validation can be carried out directly with the issuing body.

Does FDA compliance also satisfy EU food contact requirements?

Not automatically. The US framework under FDA 21 CFR and the EU framework are separate systems, and (EU) No 10/2011 is the EU framework for plastic materials intended to come into contact with food. The ZY-IML Series states migration test compliance with EU 10/2011 in addition to FDA 21 CFR, BRCGS Packaging Materials, ISO22000 and QS compliance statements, so buyers shipping to both regions should look for both dimensions in the file.

What technical parameters should be reviewed alongside the certification?

Film thickness of 30μm to 100μm (customizable), adhesion strength of at least 5N with no peeling during injection molding, temperature resistance from −20℃ to 120℃ for hot filling and cold chain, tensile strength of at least 20MPa, 4H pencil hardness scratch resistance, printing precision of ±0.1mm, 8-color high-precision rotogravure printing, and a maximum printing width of 1200mm. These values indicate whether the certified material fits the specific molding and filling process it is being bought for.

Does certification guarantee performance on my own production line?

No. The report is a material-level document. Final performance depends on the container resin, the injection molding parameters, and the filling and storage conditions at the converter's site, which is why buyers normally validate the label on their own tooling before full-scale production. Certification reduces material risk; it does not replace process validation.
