In this quick and easy guide, let’s explore a detailed list of common packaging symbols, organized by category.
Packaging symbols play a critical role in protecting consumers by providing vital information that ensures food products are handled, stored, and consumed safely.
At the most fundamental level, these symbols alert consumers to potential hazards and proper usage methods. Beyond handling instructions, symbols on food packaging often communicate important nutritional and allergen information.
Front-of-package labels, such as simplified nutrition keys or NutriScore systems, allow consumers to quickly assess the healthfulness of a product without needing to decipher detailed nutrition facts panels. Allergen warning symbols are especially crucial, as they help individuals with sensitivities avoid ingredients that could trigger severe reactions.
Moreover, certification and quality marks—such as USDA Organic or Non-GMO Project Verified—provide additional assurance regarding the production standards of food products. These marks indicate that a product has met specific safety and quality criteria, further reducing the likelihood of contamination or adulteration.
Similarly, symbols like BPA-Free or Food-Contact Safe validate that a product has undergone stringent testing to avoid chemical contamination, thereby protecting consumer health. In parallel, recycling symbols support environmental safety by guiding consumers on responsibly disposing of packaging materials, thereby minimizing ecological impact.
Collectively, these diverse symbols contribute to a safer food consumption environment. They reduce the risk of accidental ingestion of harmful substances and prevent product mishandling. Moreover, the inclusion of these symbols on packaging enhances transparency throughout the supply chain—from manufacturing to distribution and finally to the consumer’s hands. This transparency is particularly valuable in today’s market, where informed purchasing decisions hinge on clear, reliable information.
Food packaging symbols are standardized icons that deliver critical information at a glance.
Materials-related symbols are foundational in the world of packaging. They tell us at a glance what type of material has been used, which in turn speaks to its recyclability, durability, and overall suitability for food-contact applications.
1. Polyethylene Terephthalate – PET:
The #1 symbol is one of the most recognizable. PET is widely used in beverage bottles and food containers for its clarity and strength. This symbol assures consumers that the material is recyclable and meets stringent standards for safe food contact. Its durability also ensures that the product remains intact during transport, minimizing waste and reinforcing the brand’s commitment to sustainability. The numbers 1-7 indicate the different types of plastics used in beverage bottles or food containers.
2. High-Density Polyethylene – HDPE:
The #2 mark represents HDPE, a material prized for its robustness and chemical resistance. Commonly found in milk jugs and detergent bottles, HDPE is both lightweight and highly recyclable. The use of this symbol on food packaging underscores a manufacturer’s intent to use materials that can withstand daily handling while offering end-of-life recyclability.
3. Additional Material Marks:
Beyond these two, some packaging may include symbols that denote other types of plastics or composite materials. For example, specialized symbols for polypropylene or low-density polyethylene might be used in cases where the packaging design demands a unique combination of flexibility and durability. These symbols help in proper disposal and provide manufacturers with a benchmark for material performance.
These symbols facilitate a smoother recycling process and ensure that packaging complies with local waste management protocols by clearly marking the material type. They also serve as a guide for companies like Sumkoka, which seek to innovate with sustainable alternatives while still delivering high performance. Materials-related symbols are crucial in bridging the gap between production efficiency and environmental responsibility.
Health and safety symbols are indispensable when it comes to food packaging. These tags inform consumers that the packaging meets rigorous standards for chemical safety and food contact, ensuring that no harmful substances migrate into the food.
1. BPA-Free Symbol:

One of the most critical health-related marks, the BPA-Free symbol guarantees that the packaging has been manufactured without Bisphenol A—a chemical known for its potential endocrine-disrupting effects. This assurance is vital for families and health-conscious consumers, as it confirms that the product is safe for long-term contact with food.
2. Food-Contact Safe:
This symbol often represented by a glass and fork image. Alongside BPA-Free, the Food-Contact Safe label confirms that all materials used in the packaging have undergone testing and meet established safety criteria. This tag is particularly important for products that come into direct contact with food, reducing the risk of contamination and assuring quality.
3. Allergen Warnings and Nutritional Indicators:
In today’s market, consumer health extends beyond chemical safety. Packaging may also include allergen warnings to help individuals avoid ingredients that could trigger reactions. Additionally, simplified nutritional icons or traffic-light systems provide at-a-glance health information, allowing consumers to make informed dietary choices without delving into lengthy nutritional panels.
4. Regulatory and Certification Marks:
Certifications such as those from the USDA Organic or Non-GMO Project Verified often accompany health and safety symbols. These marks serve as external validations that the product has met a host of rigorous standards not only in packaging but also in production practices.
Together, these symbols form a robust framework for ensuring that food products are safe from the moment they leave the manufacturing plant until they reach the consumer’s table. They reassure buyers that every precaution has been taken to minimize health risks while promoting transparency in the production process. For companies that prioritize both quality and safety—like Sumkoka—these tags are a badge of honor, reflecting a commitment to protecting consumer well-being while adhering to high industry standards.
Handling and storage symbols are designed to preserve product integrity from the moment the package is created until it is finally delivered to the consumer. These icons provide vital instructions that help minimize damage during transportation and storage.
1. “This Side Up” and “Fragile” Symbols:
These icons are among the most commonly seen. The “This Side Up” label instructs handlers to maintain the package’s orientation, ensuring that delicate contents remain undisturbed. Similarly, the “Fragile” symbol warns of products that could easily break if mishandled. Both symbols are essential for products that require extra care, from premium foods to delicate tableware.
2. “Handle with Care” and Other Safety Marks:
In addition to orientation and fragility warnings, symbols such as “Handle with Care” provide a broader directive to treat the package gently. Such instructions can significantly reduce the likelihood of internal damage, thereby protecting the product’s quality and extending its shelf life.
3. Storage Instructions:
Some packaging includes icons that advise on proper storage conditions—indicating, for example, if the product should be kept away from direct sunlight, stored in a cool environment, or protected from moisture. These symbols are particularly relevant for food items that are sensitive to environmental conditions, helping maintain nutritional quality and safety.
4. Microwave Safe:
It's a common symbol, but there are still some people who don't know what it means. This wavy symbol is printed on everyday food containers or takeaway boxes to show that the container is suitable for microwaving and can withstand high temperatures without warping.
5. Freezer Safe:
If this symbol appears on a product or food package, it indicates that the product can be frozen in the refrigerator. It usually appears in the form of a snowflake and reminds consumers to ensure the quality of the food as well as the safety of the freezer.
By clearly communicating handling and storage requirements, these symbols reduce product waste and spoilage. They ensure that items reach their destination in optimal condition, preserving not only the product’s integrity but also the manufacturer's reputation. For eco-friendly brands committed to quality, adhering to proper handling protocols is as important as using sustainable materials.
Environmental stewardship is at the forefront of modern packaging design. Symbols that indicate recyclability and compostability are becoming increasingly common, reflecting both regulatory demands and consumer expectations.

The classic recycling symbol—a triangle of chasing arrows—communicates that the packaging material can be reprocessed. Often accompanied by a number or percentage, this icon informs the consumer of the material’s recycled content or the type of plastic used, which aids in the proper sorting and recycling process.
2. Compostable and Biodegradable Symbols:
As sustainability becomes more than a buzzword, packaging often carries a compostable symbol—typically a leaf or plant icon—to indicate that the material will break down naturally under proper conditions. This is crucial for products aimed at reducing landfill waste and minimizing long-term environmental impact.
3. Sustainable Sourcing Certifications:
Symbols such as the FSC (Forest Stewardship Council) Certified mark verify that the packaging material has been sourced from responsibly managed forests. This certification reinforces the message that the product not only cares about its immediate safety but also about the long-term health of the environment.
Environmental and recycling symbols serve as a visible commitment to sustainability. They guide consumers on how to dispose of packaging responsibly, promote recycling practices, and help foster a circular economy. For brands like Sumkoka’s bagasse tableware, integrating these icons into their packaging strategy is an essential part of demonstrating a commitment to a greener future.
