Test Report on Adhesive for Paper Tube Production
Unveiling the “Invisible” Guardians of High-Quality Paper Tube Packaging: International Safety Standards Through RoHS and SDS Reports In the global B2B trade, when brands procure paper packaging, they are often first drawn to unique designs, exquisite printing techniques, or sturdy construction. However, as a professional paper tube manufacturer based in Guangzhou
Sprintpackage understands that what truly determines whether a cylindrical package is internationally competitive and can pass the rigorous inspections of customs authorities worldwide are often the “invisible” details hidden beneath the glamorous exterior—such as the adhesives essential for forming the paper tubes.
Whether for food, cosmetics, health supplements, or clothing and wine bottle packaging, safety and environmental friendliness are always non-negotiable red lines. Today, through detailed Safety Data Sheets (SDS) and authoritative SGS test reports, we will provide an in-depth analysis of SprintPackage’s rigorous control over adhesives during production, and how we help your brand achieve worry-free global expansion.
1. Eliminating Hidden Hazards
SGS-Certified RoHS Environmental Commitment In international trade and logistics, the chemical safety of packaging materials directly determines whether a product can successfully clear customs declarations and be legally marketed in the destination country. To ensure that every batch of paper tube packaging delivered to our customers meets the highest safety standards, the adhesives we use in production have undergone rigorous testing by the authoritative third-party testing agency SGS. According to the latest test reports, our paper tube adhesive fully complies with the stringent requirements of the amended EU RoHS Directive 2015/863, which amends Annex II of Directive 2011/65/EU. In specialized testing for ten high-risk hazardous substances, the results showed “Not Detected (ND)” for all substances, and the conclusion was “Compliant.” These strictly excluded hazardous substances include: Four major heavy metals: Lead (Pb), Mercury (Hg), Cadmium (Cd), and Hexavalent Chromium (Cr(VI)). Two major flame retardants: Polybrominated biphenyls (PBB) and Polybrominated diphenyl ethers (PBDE). Four major phthalates (plasticizers): Di(2-ethylhexyl) phthalate (DEHP), butyl benzyl phthalate (BBP), dibutyl phthalate (DBP), and diisobutyl phthalate (DIBP). This means that, starting from the procurement stage, we have completely eliminated the introduction of toxic heavy metals and non-compliant plasticizers. This commitment to compliance not only reduces compliance risks for brands during import tax refunds and customs clearance but also demonstrates a high level of responsibility toward the health of end consumers.
2. Transparent Chemical Composition
A Safe Foundation for Water-Based Eco-Friendly Formulations In addition to overcoming technical barriers in international trade through RoHS certification, the physical and chemical properties of this specialized adhesive itself demonstrate an exceptionally high level of environmental sustainability. According to the Safety Data Sheet (SDS) for this paper tube adhesive, it is a pale yellow liquid with only a faint odor. Its core components are highly pure and transparent, consisting primarily of the following substances: Water (70.5%): As the main solvent, it ensures the adhesive’s eco-friendly properties. Kaolin (15%): A natural mineral that provides the necessary physical filling and bonding strength. Polyvinyl alcohol (8%) and starch (6.5%): Safe polymers and natural carbohydrates that work together to form an excellent bonding network. The SDS report further confirms that this product is non-flammable and poses absolutely no fire risk. Under normal conditions of use, storage, and transportation, it remains stable and does not produce any hazardous decomposition products. This water- and natural mineral/starch-based formulation significantly reduces the release of volatile organic compounds (VOCs), perfectly aligning with the global market’s strong demand for sustainability and eco-friendly packaging.
3. Ensuring Food-Grade Packaging Safety
The Case of the Version 2.0 Sushi Paper Tube When it comes to packaging that comes into direct or indirect contact with food, the importance of material safety cannot be overstated. At sprintpackage’s state-of-the-art production facility in Guangzhou, we recently achieved a technological breakthrough by successfully mass-producing the fully upgraded Version 2.0 sushi paper tube. Designed specifically for high-end Japanese takeout and supermarket retail, this packaging features revolutionary structural innovations: not only does it achieve exceptional sealing performance that virtually eliminates sauce leakage, but it also incorporates a cleverly designed black clip inside to securely hold the sauce tube in place, significantly enhancing the dining experience for end consumers. More importantly, to meet extremely stringent food contact safety standards, the inner wall of this sushi paper tube employs a high-specification aluminum-laminated inner tube process, designed to fully comply with the EU’s EC 1935/2004 certification for food contact materials. When manufacturing such high-end paper tubes with rigorous food safety requirements, the adhesive used in forming the outer tube paper must never become the “weakest link” in the “wooden bucket principle.”
It is precisely because of this eco-friendly, water-based paper tube adhesive—free of toxins, heavy metals, and non-compliant plasticizers—that we can fundamentally prevent harmful chemicals from penetrating the inner aluminum foil or causing potential chemical migration. Although the adhesive itself does not come into direct contact with the sushi, this comprehensive, toxin-free supply chain management system—covering every aspect from the inside out—is the cornerstone of sprintpackage’s trust among numerous international food brands.
