Application of Handheld Large Characters on PP Bags

Application of Handheld Large Characters on PP Bags

In the agricultural materials, chemical, food and other industries that use PP bags for packaging, labels are not only the carrier of product information, but also the "pass" for enterprises to operate in compliance. The mandatory requirements of laws and regulations for packaging labels determine that PP bags must have clear and standardized printing content, and Faith handheld large-character inkjet printers have become an ideal solution to meet this demand with their professional performance.

1. Laws and regulations: Rigid constraints on PP bag labelsAs an important packaging form for industrial products and consumer goods, PP bags are strictly regulated by a number of laws and regulations. Missing or non-standardized labels will face clear penalties:

Product Quality Law: It requires that product packaging must be marked with core information such as production date, shelf life, manufacturer, and implementation standards. If the PP bag is not marked or the marking is unclear, it will be identified as an "unqualified product" and face confiscation of illegal income, fines, and other penalties. In serious cases, the production license may be revoked.
Industry-specific regulations: For example, the "Content and Requirements of Fertilizer Labeling" (GB 18382-2001) in the agricultural materials field clearly stipulates that fertilizer PP bags must be labeled with product name, ingredient content, production license number, warning words, etc., and the text height must not be less than 3mm to ensure that farmers can clearly identify them; chemical products must comply with the "Regulations on the Safety Management of Hazardous Chemicals" and label PP bags with hazardous characteristics, emergency measures and other information.
Traceability system requirements: According to the "Opinions of the State Council on Accelerating the Construction of Important Product Traceability Systems", key products such as food and agricultural materials must achieve "source traceability and destination traceability" through packaging labels. The batch number and traceability code on PP bags become mandatory requirements, and substandard products are not allowed to enter the market.
These regulations together constitute the "bottom line requirements" for PP bag labels, and the clarity and durability of the printing are the basis for compliance - vague production dates and batch numbers that are easy to fall off may cause products to be judged as "non-compliant", bringing business risks to enterprises.

2. Core content that must be printed on PP bags

Based on the above laws and regulations and circulation needs, the printed content on PP bags must cover three categories of core information, none of which can be missing:
Basic compliance information: including production date (such as "2025/07/09"), shelf life ("shelf life 18 months"), production license number ("XK13-001-XXXX"), implementation standard ("GB/T 2001-2020"), etc. These information are the "access permit" for the legal listing of the product and must be permanently clear and identifiable.
Traceability management information: batch number ("Batch-20250709-03"), traceability QR code/barcode, serial number ("SN20250709001") are the key to achieving full-chain traceability, which can be associated with data such as raw material procurement, production process, quality inspection report, etc. Once a quality problem occurs, the source can be quickly located and recalled.
Product characteristics and safety information: According to the characteristics of the contents of the PP bag, the product name ("compound fertilizer"), specifications ("50kg/bag"), ingredients ("N-P-K 15-15-15"), storage requirements ("moisture-proof and sun-proof"), safety warnings ("keep away from children"), etc. need to be marked to guide downstream users to use and manage correctly and reduce the risk of misuse.
These contents need to be flexibly adjusted according to the size of the PP bag - small-sized PP bags can choose single-line key information, while large-sized PP bags need to be arranged in multiple lines to ensure that the information is complete and easy to read.

3. Faith handheld large character inkjet printer: the core tool for compliant printing

Faith handheld large character inkjet printer (H16, H32 models) is specially designed for compliant printing of PP bags, and perfectly adapts to the printing needs of the above content:
Compliance guarantee: equipped with industrial-grade nozzles and special inks, the minimum height of the printed characters is 10mm, which meets the regulatory requirements for "clear and legible"; oil-based ink is designed for the non-permeable surface of PP bags, and the adhesion strength reaches the industry standard. After friction and water washing tests, it remains intact, avoiding compliance risks caused by blurred logos.
Content adaptability: The H16 model supports 10-60mm character height adjustment, and can print single-line long characters (such as production license number) or double-line numbers/English (such as production date + batch number); the H32 model character height can reach 10-124mm, and supports up to 4 lines of dot matrix characters, which can fully present multi-line long texts such as ingredient lists and safety warnings, and adapt to the needs of large-size PP bags.
Flexible operation features: The device weighs only 1.5-2kg and can be operated by hand without a fixed production line. It is suitable for printing in multiple scenarios such as warehouses, workshops, and fields; 360° printing direction adjustment, which can accurately print on the plane, side, and even curved surface of PP bags, solving the problem of labeling special-shaped packaging; built-in real-time clock and batch counting function, automatically increment the number during batch printing, reducing manual operation errors.
Environmental adaptability: The integrated injection molding body is wear-resistant and drop-resistant, and can work stably in an environment of 5℃-45℃, adapting to the temperature difference of warehouses where PP bags are stored, outdoor exposure, and other scenarios; the TYPE-C interface is equipped with a waterproof and dustproof rubber plug to prevent dust and water vapor from affecting the life of the equipment and reduce maintenance frequency.

4. The unique value of the Faith solution: a comprehensive upgrade from compliance to efficiency

Compared with traditional identification methods (template stamping, sticker labels), the Faith handheld large-character inkjet printer brings irreplaceable advantages to PP bag printing:
Lower compliance costs: no plate-making costs are required, and template design and replacement costs are eliminated; ink consumption is only 0.04 yuan/bag, which is much lower than the cost of label materials and manual pasting, and small batch orders can also achieve low-cost compliance.
More flexible response to demand: support instant modification of printing content, such as changing batch numbers and adjusting specification information, without stopping for debugging, adapting to the "multi-batch, small-batch" production rhythm of agricultural materials peak season, and avoiding production capacity loss due to label adjustment.
Controllable risks throughout the process: The label is integrated with the PP bag, without the risk of falling off or fading. Even after long-distance transportation and open-air storage, the full life cycle data can still be quickly associated by scanning the traceability code to meet the traceability verification requirements of the regulatory authorities.
Brand trust bonus: Clear and standardized logos reflect the company's emphasis on compliance, enhance the trust of downstream customers (such as farmers and distributors) in product quality, and indirectly enhance brand competitiveness.
