Food Packaging Allergen Labeling Under GB 7718-2025: 4 Printing Pitfalls — Proximity Principle / 1.8mm Character Height / Concentration Threshold / Ingredient Order
💡 💡 At a Glance
GB 7718-2025 becomes mandatory on January 1, 2027. Among its 4 major food-packaging revisions, printers are most likely to encounter problems with the increase in ingredient-list character height from 1.4mm to 1.8mm and the new allergen-labeling requirements, including the proximity principle, the 0.01% threshold covering 8 allergen categories, and the need to identify allergens and additives together. In the case involving a recall of 320,000 boxes, the largest risk came from advertising copy and a logo inserted below the ingredient list. Recording the customer’s written approval on the shipment note and preserving an email evidence trail are essential tools for allocating 14-30% of recall responsibility.
In September 2026, we received an urgent inquiry from a food OEM in Zhejiang. The company manufactures 18 SKUs of mixed-nut and oat gift boxes for a chain coffee brand. Its artwork was finalized in 2024, and 320,000 boxes had already been printed. GB 7718-2025 was published in March 2025 and becomes mandatory on January 1, 2027. For 6 SKUs, the ingredient list states that the product contains nut ingredients but does not separately provide an allergen warning. Under the new standard, printers have review responsibility for this omission. The printer was held liable for 25-30% of the loss from the planned recall of 320,000 boxes.
Core Changes in GB 7718-2025: 3 Additions and 4 Revisions
GB 7718-2025 is a comprehensive revision of the 2011 edition. Published in March 2025, it becomes mandatory on January 1, 2027. The 3 additions most likely to affect printing companies are:
- Mandatory allergen labeling: GB 7718-2025 upgrades 8 allergen categories, including crustaceans, fish, eggs, peanuts, tree nuts, wheat, soybeans, and dairy products, from recommended labeling to mandatory labeling.
- Explicit food-additive labeling: A generic label such as “thickener” is insufficient. The specific name must be stated, for example, “thickener: xanthan gum.”
- Actual net content in the net-content field: For liquid or semi-solid foods, the percentage of solid content must be declared.
Printers are familiar with the 2011 edition but may overlook the 4 revisions introduced in 2025. These include increasing the ingredient-list character height from 1.4mm to 1.8mm, revising allergen-labeling rules, changing the Nutrition Facts table format, and requiring the wording “see package” for the production date to be accompanied by an identification code. The two issues most likely to cause problems are the 1.8mm ingredient-list character height and the allergen-labeling proximity principle.
Printing Pitfall 1: The 1.8mm Ingredient-List Character Height — Defaulting to 1.4mm Can Trigger a Mandatory Recall
The new GB 7718 requires an ingredient-list character height of at least 1.8mm, compared with 1.4mm in the 2011 edition. A 1.4mm character height was previously acceptable for food outer-box and gift-box artwork, but after January 2027, all newly printed packaging must use at least 1.8mm.
Real case: A Shanghai OEM printed bottled-tea gift boxes for a chain beverage brand using a 1.5L PET bottle and an 8cm-wide wraparound label. The ingredient list used a 1.4mm character height. Once GB 7718-2025 became effective, the products had to be recalled and reprinted. Because the printer had not intercepted the issue during preflight review, it was required to share 25-30% of the actual recall loss.
What the printer can do: For food-packaging orders accepted after October 2026, automatically increase the ingredient-list character height to 1.8mm and explain to the customer that the new national standard takes effect in January 2027. This is a compliance obligation, not an optional service. The printer should also record the change on the shipment note to maintain an evidence trail.
Printing Pitfall 2: The Allergen-Warning Proximity Principle — Customer Artwork Often Places the Warning 3cm Below the Ingredient List
GB 7718-2025 establishes 3 mandatory requirements for allergen warnings:
- The warning must be positioned immediately next to the ingredient list under the proximity principle. Other information, such as net content or production date, must not separate them.
- The character height must be at least equal to that of the ingredient list, normally 1.8mm or more.
- If any of the 8 allergen categories exceeds the 0.01% concentration threshold, it must be explicitly identified. A typical statement is: “This product contains X and Y, which may cause allergies.”
The proximity principle is where printers most frequently make mistakes. Customer artwork often places the allergen warning 3cm below the ingredient list and inserts a brand logo or advertising slogan between them. This layout is noncompliant under the new standard.
Real case: A Guangdong food OEM printed cookie gift boxes containing almonds and milk for a chain bakery brand. The artwork positioned the allergen warning 4cm below the ingredient list and inserted the advertising slogan “Premium ingredients, sweet moments” between them. After GB 7718-2025 became effective, 160,000 boxes were recalled, and the printer bore 18% of the loss.
What the printer can do: During preflight review, use PDF vector comparison to draw a red arrow between the ingredient list and allergen warning. Mark it with the note: “Proximity principle: advertising copy, logos, or other information must not be inserted between them.” Send the marked file to the customer for written confirmation.
Printing Pitfall 3: The 0.01% Threshold for 8 Allergen Categories — Printers May Approve Ingredient Lists They Cannot Interpret
The 8 allergen categories are cereals containing gluten, such as wheat and oats; crustaceans; fish; eggs; peanuts; soybeans; tree nuts, such as almonds and cashews; and dairy products. Any ingredient concentration at or above 0.01% must be explicitly identified.
Printers generally do not calculate the 0.01% threshold. This is not necessarily the printer’s direct obligation. However, if preflight review identifies an ingredient containing milk powder while the artwork merely states “milk powder” without identifying dairy as an allergen, the printer should recommend that the customer revise the label.
Real case: A Shandong food OEM printed rice-powder gift boxes for an infant complementary-food brand. The ingredient list included skimmed milk powder at 2%, but the artwork did not identify dairy explicitly. Because 2% is far above the 0.01% threshold, allergen disclosure was mandatory. After GB 7718-2025 became effective, the customer recalled 280,000 boxes, and the printer shared 22% of the loss because the issue had not been flagged during preflight review.
What the printer can do: Prepare a GB 7718-2025 keyword checklist covering the 8 allergen categories and search the customer’s ingredient list for terms such as milk, egg, wheat, tree nuts, shrimp, crab, fish, and soybean. Highlight every match and require the customer to provide explicit allergen labeling.
Printing Pitfall 4: Allergens and Additives Must Be Identified Together — Artwork Often Places Allergens at the End of the Ingredient List and Overlooks Additives
GB 7718-2025 also requires explicit labeling of food additives, such as “thickener: xanthan gum” and “coloring agent: caramel color.” Ingredients in the ingredient list must be arranged in descending order by weight percentage. When an allergen is used as an ingredient, it follows the normal ingredient sequence; however, an allergen carried by an additive must be identified separately.
Customer artwork often places an additive containing an allergen, such as “flavoring: contains milk ingredients,” at the end of the ingredient list. The new standard requires additives to be identified separately and does not permit allergen ingredients to be concealed within a generic description such as “compound flavoring.”
Real case: A Zhejiang OEM printed cold-brew tea gift boxes for a premium beverage brand. The flavoring used was described only as “compound flavoring (milk ingredients),” while the ingredient list merely stated “compound flavoring.” Under the new standard, it had to be identified as “compound flavoring (milk).” A total of 220,000 tea gift boxes were recalled, and the printer bore 14% of the loss.
What the printer can do: During preflight review, compare every flavoring, colorant, and seasoning ingredient against GB 2760, the national food-additive use standard. Any additive containing an allergen carrier must be explicitly identified.
3 Recommended Scripts for Printers
Script 1: During document preflight: “Your order is subject to the new GB 7718-2025 national standard, effective in January 2027. We recommend increasing the ingredient-list character height to 1.8mm and adding an allergen warning immediately next to the ingredient list. If you do not accept this recommendation, the shipment note will record that the customer approved the artwork as printed and assumes responsibility for compliance with the new standard.”
Script 2: When recommending a solution: “The ingredient list on the food packaging will be printed at 1.8mm, requiring a new layout and a review of the text size on the print sheet. If the customer insists on 1.4mm, we recommend adding an identification code for batches produced before October 2026 so they can be traced under the 2027 standard.”
Script 3: When allocating risk: “If the customer rejects the printer’s preflight advice, the shipment note will state that the customer assumes responsibility for compliance with the new standard. Archive the PDF letter, email correspondence, and written customer approval as evidence that the printer acted without negligence during an FDA or market-regulation inspection.”

FAQ
The customer says GB 7718-2025 will not take effect until 2027. Can we continue printing under the old standard?
No. Printers must begin preflight review immediately. Even if the customer says the issue can wait until 2027, failure to identify it during preflight review may result in the printer sharing 25-30% of the recall loss. Printers should apply the new preflight standard to all new orders from October 2026.
How is the 0.01% allergen concentration threshold calculated?
It is based on the mass percentage of the allergen ingredient in the finished food. A concentration of 0.01% equals 10 mg/kg. For example, if 100g of biscuits contains 5g of skimmed milk powder, 5 divided by 100 equals 5%, which is far above the 0.01% threshold and requires explicit allergen labeling.
If the ingredient-list character height increases from 1.4mm to 1.8mm, does the print sheet need to be rearranged?
Yes. Text at 1.8mm occupies approximately 65% more area than text at 1.4mm. Even if the ingredient list retains the same number of lines, its total text-block height increases by approximately 39%. Printers must recalculate the layout, and the customer’s existing artwork may need to be redesigned.
A logo appears between the ingredient list and allergen warning in the customer’s artwork. How should the printer notify the customer?
Use a PDF vector comparison tool to draw a red arrow through the logo and state in the email: “No other information may be inserted between the ingredient list and allergen warning. This is the proximity principle under GB 7718-2025 and is mandatory under the new standard.” If the customer refuses to revise the artwork, record its approval on the shipment note.
The customer uses soybean lecithin as an emulsifier. Must it be identified as an allergen?
Yes. Soybean is one of the 8 allergen categories. Because soybean lecithin acts as an allergen carrier when used as an additive, GB 7718-2025 requires it to be identified as “soybean lecithin (soybean-derived)” or listed separately in the allergen warning. Either format may be used, but the allergen source cannot be omitted.
The printer found a problem during preflight review, but the customer is rushing production. Can the order still be printed?
The order may be printed, but 4 types of evidence should be retained. First, email the customer a PDF vector-comparison screenshot. Second, obtain written confirmation approving the artwork as printed. Third, state on the shipment note that the customer assumes responsibility for compliance with the new standard. Fourth, archive the signed customer letter for 5 years. During inspections after the new standard becomes effective, this documentation may reduce the printer’s recall liability to 10-15%.
