1. The International Standard System Framework: How ISO and regional standards work together
The International Organization for Standardization (ISO), the European Committee for Standardization (CEN), and national standardization organizations work together to set the international standards for molded pulp packaging. These standards cover safety, performance, and environmental protection.
General Standards from ISO
ISO 18601 "Pulp molded products - General requirements" is a widely accepted core standard that sets out the rules for the raw materials used to make molded pulp packaging (for example, it says that heavy metals and fluorescent whitening agents are not allowed), the physical properties (for example, it says that the packaging must be able to withstand pressure, drop strength, and dimensional deviation), and the hygiene indicators (for example, it says that the packaging must not have any microbial limits or solvent residues). For instance, this guideline says that when packaging touches food, the amount of heavy metals like lead, cadmium, and mercury that can go from the packaging to the food must be less than 10mg/kg. This is in line with the EU PPWR rule.
Standards for strengthening regions
EU PPWR Rule: The "Packaging and Packaging Waste Regulation" will be fully in effect by 2026. It makes molded pulp packaging meet stricter standards.
Chemical safety: It is against the law to use perfluorinated and polyfluoroalkyl substances (PFAS) if the concentration of one PFAS is < 25 ppb and the total fluorine content is ≤ 50 ppm;
Recyclability: The packaging's porosity shouldn't be more than 50%, although the porosity of molded pulp packaging can be kept to 30% because of the way it is made;
Starting in 2030, food packaging must contain 30% recycled materials. Molded pulp packaging naturally fits this criteria because it is made from renewable fibers.
Standard set by the US FDA: The FDA 21 CFR Part 176 says that molded pulp used in food contact packaging must pass a simulated migration test to make sure that no dangerous compounds are released at a high temperature of 100 °C. Also, the container surface must be smooth and not shed fibers to keep food from getting dirty.
Standards that are specific to an industry
IPC-A-610 "Acceptability Standards for Electronic Components" says that molded pulp packaging must go through vibration testing (frequency 10-55Hz, amplitude 1.5mm) and high temperature and high humidity testing (85 °C/85% RH, 48 hours) to protect precision parts. For instance, the packaging for a certain brand of drone propellers has a honeycomb support structure with a compressive strength of 120kPa, which is much higher than what is required.
2, Key technical indicator: complete management of the process from raw materials to final goods
International standards oversee molded pulp packaging all the way from raw materials to production and testing. Some of the most important indicators are:
Safety of raw materials
Fiber source: Use renewable raw materials such waste paper, sugarcane bagasse, bamboo fiber, etc. instead of recycled medical waste or industrial waste that contains heavy metals.
Additive restrictions: The EU PPWR law makes it illegal to employ dangerous chemicals like PFAS and bisphenol A (BPA). The US FDA, on the other hand, authorizes the use of waterproofing agents that are GRAS (generally considered safe), such chitosan and starch-based coatings.
Properties of the body
ISO 18601 says that packaging must be able to handle static pressure equal to "mass of transport packaging x storage height (usually 3m) x deterioration coefficient (1.6-2.0)." For instance, a certain type of laptop packing has made its pressure resistance 30% better by changing the way the fibers are arranged;
Drop strength: The product must pass the "one corner, three edges, six sides" drop test from a height of 0.8 to 1m. The function and appearance of the product inside the container must not be destroyed. In a drop test from 1.5 meters, a certain brand of mobile phone packaging had a product integrity percentage of 99.2%.
performance for the environment
Degradability: It must meet the EU EN 13432 standard, which says that the composting degradation rate must be at least 90% after 180 days and that the end product must not be harmful to the environment.
Carbon footprint: The International Organization for Standardization is working on ISO 14067, the "Product Carbon Footprint Quantification Standard." This standard will oblige packaging firms to share all of their carbon emissions data from the time they buy raw materials until they throw them away.
3, Different rules in different regions: how the EU, the US, and China get into markets
diverse markets have very diverse rules for molded pulp packaging, thus enterprises need to change their product strategy to fit those rules.
EU market: stringent rules on protecting the environment and being able to be recycled
PPWR regulation: Starting in 2026, every packaging must have information on what materials it is made of and utilize a single pictographic label. From 2029 forward, reusable packaging must include clear labels and a QR code that leads to a recycling guide. Molded pulp packaging meets consumers' cognitive needs because it is made up of only one type of material (mostly plant fibers) and has clear label information. For example, the packaging for a certain brand of headphones is made from natural bamboo fiber and is labeled as "made from 3 sugarcane." This has led to spontaneous sharing on social media and improved the brand's environmental image.
In the US market, safety and performance are equally important.
FDA certification: Packaging that comes into contact with food must pass the 21 CFR Part 176 test and meet the ASTM D6400 "Compostable Plastic Standard." For example, a certain brand of fast food packaging uses molded pulp meal boxes, which have passed FDA certification and successfully replaced traditional plastic meal boxes, increasing market share by 25%.
Chinese market: pushed by legislation and standard upgrades
The national standard is GB/T 42943-2023. "Technical specifications for pulp molded products" lists the pressure resistance, drop strength, and other standards for packaging that doesn't come into contact with food. "National Food Safety Standard - Food Contact Paper and Paperboard Materials and Products" lists the hygiene standards for packaging that does come into contact with food.
Support for policy: The "Technical Requirements for Energy Consumption per Unit Product of Pulp Molding Products" standard that will go into effect in July 2025 will encourage businesses to use less energy and make their production more efficient.
