35+ Packaging Symbols and Their Meanings Explained

Why Are Packaging Symbols Important?

Packaging symbols share information quickly and visually. They are especially helpful when products travel internationally or are handled by people who speak different languages.

The main purposes of packaging symbols include:

• Safety: Communicating handling precautions and product risks.

• Material identification: Showing what a package is made from.

• Recycling guidance: Providing information about material recovery and disposal.

• Transportation: Explaining how packages should be stored, lifted, or moved.

• Compliance: Supporting applicable packaging, product, and environmental requirements.

Not every symbol has the same legal status. Some are voluntary marks, while others may be connected to specific regulations or certification programs.

35+ Common Packaging Symbols and Their Meanings

There are five main types of packaging symbols: recycling and environmental symbols, material codes, safety marks, handling instructions, and transportation symbols.

Recycling and Environmental Symbols

1. Recycling Symbol (Mobius Loop)

The Mobius loop consists of three arrows forming a triangle. It is commonly associated with recycling and recyclable materials.

But this symbol does not always mean your package will be accepted by local recycling centers. Whether it can be recycled depends on the material and the local recycling system.

2. Recycled Content Symbol

This symbol or claim indicates that a package contains recycled material.

The amount of recycled content can vary. Businesses should provide specific, accurate information instead of implying the entire package is made from recycled materials.

3. Recyclable Paper Symbol

A paper recycling symbol identifies packaging made from paper or indicates an association with paper recycling.

Paper packaging may not be accepted in every recycling system if it contains coatings, adhesives, food residue, or other materials.

4. Recyclable Glass Symbol

This symbol is associated with glass recycling. It is often found on glass bottles, jars, and other containers.

Whether the item can be recycled depends on local collection and processing requirements.

5. Green Dot Symbol

The Green Dot symbol is associated with participation in a packaging recovery system in certain markets.

It does not automatically mean the packaging is recyclable. Its meaning depends on the national system and conditions under which the mark is used.

6. Tidyman Symbol

The Tidyman symbol shows a person placing waste into a bin.

It encourages people to dispose of packaging responsibly and avoid littering. It does not indicate that the packaging itself is recyclable.

Plastic and Material Identification Symbols

7. Resin Identification Code

The Resin Identification Code, or RIC, is usually displayed as a number inside a triangular symbol.

The number identifies the type of plastic resin used in the product. It is a material identification system, not a guarantee the item can be recycled in a particular location.

8. PET or PETE (Code 1)

Polyethylene terephthalate, commonly known as PET or PETE, is used in beverage bottles, food containers, and other packaging.

It is lightweight and durable, and it is widely collected in some recycling systems. Acceptance varies by location.

9. HDPE (Code 2)

High-density polyethylene, or HDPE, is used in bottles, containers, and durable plastic packaging.

It is valued for its strength and resistance to moisture. Recycling availability depends on the local waste management system.

10. PVC (Code 3)

Polyvinyl chloride, or PVC, is used in certain packaging and industrial applications.

PVC products require appropriate sorting and processing because their composition differs from other common packaging plastics.

11. LDPE (Code 4)

Low-density polyethylene, or LDPE, is a flexible plastic used in films, bags, wraps, and some packaging materials.

Flexible plastics may not be accepted through standard household recycling collections, so local guidelines should be checked.

12. PP (Code 5)

Polypropylene, or PP, is commonly used for food containers, caps, tubs, and other packaging products.

Its recycling acceptance depends on the collection and processing infrastructure available in the area.

13. PS (Code 6)

Polystyrene, or PS, is used in some protective packaging and food-service products.

Certain forms of polystyrene can be difficult to recycle because of their structure, volume, or contamination.

14. Other Plastics (Code 7)

Code 7 identifies plastics that do not fall into the first six categories or that contain certain combinations of materials.

The code does not identify one specific plastic type. Additional material information may be needed to determine how the item should be handled.

Safety and Certification Symbols

15. Food-Safe Symbol

A food-safe symbol or claim indicates that packaging is intended or approved for use with food under specified conditions.

Food-contact requirements vary by material, product, and market. Businesses should verify the relevant documentation before making food-safety claims.

16. CE Mark

The CE mark indicates that a manufacturer declares conformity with applicable European Union requirements for products covered by relevant legislation.

It is not a universal symbol for all packaging. Whether it applies depends on the product and the regulations governing it.

17. Child-Resistant Packaging Symbol

Child-resistant packaging is designed to make it more difficult for children to open certain products.

The requirements depend on the product category, packaging design, and applicable regulations. A symbol does not replace required testing or compliance procedures.

18. Tamper-Evident Packaging Symbol

Tamper-evident packaging is designed to show visible evidence when a package has been opened or interfered with.

Examples include seals, bands, labels, and specially designed closures. The appropriate solution depends on the product and the protection it requires.

Environmental Certification and Sustainability Symbols

19. Compostable Symbol

A compostable symbol indicates that a material is designed to break down under specified composting conditions.

Some compostable packaging requires industrial composting facilities. It should not automatically be assumed that it will break down in a home compost pile or in the natural environment.

20. Biodegradable Symbol

Biodegradable refers to a material's ability to break down through biological processes under defined conditions.

The term alone does not explain how quickly the material breaks down or what environmental conditions are required. Businesses should support environmental claims with relevant evidence.

21. FSC Symbol

The Forest Stewardship Council (FSC) mark is associated with responsibly sourced forest-based materials.

Businesses using FSC-certified packaging must follow the applicable certification and trademark requirements.

22. Recycled Material Claim

A recycled material claim communicates that a package contains recovered material, such as recycled paper or plastic.

The claim should accurately describe the type and amount of recycled content. Recycled content and recyclability refer to different characteristics.

For businesses exploring packaging options, Arka's packaging solutions  offer different formats for product presentation and shipping.

Handling and Shipping Symbols

23. Fragile Symbol

The fragile symbol usually shows a broken glass.

It indicates that the contents may be breakable and should be handled carefully. The symbol provides a handling instruction but cannot guarantee that a package will avoid all impact during transit.

24. Handle With Care Symbol

This symbol communicates that the package requires careful handling.

It may be used for delicate products or shipments that could be damaged by rough movement or improper storage.

25. Keep Dry Symbol

The keep-dry symbol is commonly represented by an umbrella.

It indicates that the package should be protected from rain, moisture, or wet conditions. Additional moisture-resistant packaging may be needed for sensitive contents.

26. Protect From Sunlight Symbol

This symbol advises handlers to keep the package away from direct sunlight.

It may be used for products that can be affected by heat, ultraviolet exposure, or prolonged light exposure.

27. Temperature Warning Symbol

A temperature warning symbol indicates that a product may require specific temperature conditions.

For temperature-sensitive items, the package should include clear instructions about the acceptable temperature range when necessary.

28. Do Not Stack Symbol

The do-not-stack symbol indicates that packages should not be placed on top of one another.

This instruction is useful when stacking could damage the contents or compromise the package.

29. Maximum Stacking Height Symbol

This symbol indicates the maximum number of packages or the height at which packages can be stacked.

The permitted limit should be clear to warehouse and transportation teams.

30. Do Not Hook Symbol

The do-not-hook symbol warns handlers not to use hooks when moving the package.

Hooks can puncture, tear, or otherwise damage certain types of packaging.

31. Do Not Lift Symbol

This symbol communicates that a package should not be lifted in a particular way or from a specific location.

It should be considered alongside any written lifting and handling instructions.

32. Do Not Open With a Sharp Object Symbol

This symbol warns recipients against using knives, scissors, or other sharp tools to open the package.

It can help reduce the risk of damaging the product inside during unpacking.

33. Do Not Freeze Symbol

The do-not-freeze symbol indicates that the contents should not be exposed to freezing temperatures.

It may be relevant to certain liquids, food products, cosmetics, and other temperature-sensitive goods.

Special Transportation Symbols

34. Two-Person Lift Symbol

This symbol indicates that two people should lift the package.

It is generally used when a package is too heavy or difficult for one person to handle safely.

35. Trolley Symbol

A trolley symbol recommends using a cart or trolley to move the package.

It can be useful for communicating the preferred method of transporting heavy or bulky items.

36. Center of Gravity Symbol

The center-of-gravity symbol shows where the package's weight is concentrated.

It helps handlers position and move the package safely, particularly when the contents are unevenly distributed.

37. Package Weight Symbol

This symbol communicates the weight of a package or indicates that weight information is relevant to handling.

Specific weight details should be provided when they are necessary for lifting, storage, or transportation.

38. Keep Away From Magnets Symbol

This symbol warns that the package should be kept away from magnets or strong magnetic fields.

It may be used for products that could be damaged or affected by magnetic exposure.

How to Use Packaging Symbols Correctly

Adding a symbol to a package is not enough. Businesses should make sure that the mark accurately reflects the product, packaging material, and applicable requirements.

Verify the Symbol's Meaning

Some symbols may look similar but communicate different information. Check the meaning and usage requirements before printing a mark on packaging.

Review Local Regulations

Packaging regulations vary by country, product category, and industry. A symbol that is common in one market may have different requirements in another.

Avoid Unsupported Environmental Claims

Terms such as recyclable, compostable, biodegradable, and sustainable should be used carefully.

Ensure that environmental claims are accurate, specific, and supported by appropriate documentation.

Make Symbols Visible

Symbols should be large and clear enough to read. Consider their size, contrast, placement, and the surface on which they will be printed.

Add Written Instructions When Needed

Symbols do not always provide enough detail. Add written instructions when a package requires specific storage temperatures, lifting limits, disposal instructions, or safety precautions.

How Packaging Design Supports Better Communication

Packaging design is about more than adding a logo or selecting a color scheme. The structure, materials, labels, and printed instructions all influence how customers and shipping teams interact with a package.

A well-designed package can help businesses:

• Communicate handling instructions.

• Present important product information.

• Improve brand recognition.

• Support product protection.

• Create a consistent unboxing experience.

• Organize shipping and fulfillment.

For products that need additional structural support, Arka's custom shipping boxes  offer an option for combining product protection with branded packaging.

Businesses can also explore custom mailer boxes  for shipments that need both presentation and practical shipping functionality.

For additional protection inside the package, custom packaging inserts  can help hold products in place and create a more organized unboxing experience.

Brands can also use custom stickers  to add branding, product information, or visual details to their packaging.

Packaging Symbols and Sustainability

Packaging symbols can help people make more informed decisions, but a single symbol cannot describe a package's complete environmental impact.

Other factors include:

• The materials used.

• The amount of material required.

• Manufacturing processes.

• Transportation distance.

• Recycled content.

• Opportunities for reuse.

• Local recycling and composting infrastructure.

• End-of-life disposal.

For example, a package may be technically recyclable but not accepted by a local recycling program. Similarly, compostable packaging may require access to a commercial composting facility.

Businesses should evaluate the full packaging lifecycle instead of relying on one symbol to communicate overall sustainability.

How to Choose the Right Packaging for Your Business

The right packaging depends on the product, shipping method, brand requirements, and level of protection needed.

Before selecting packaging, consider:

1. Product dimensions: Choose packaging that fits the product without excessive empty space.

2. Product weight: Make sure the packaging can support the contents.

3. Fragility: Add inserts or cushioning when the product needs extra protection.

4. Shipping conditions: Consider moisture, handling, temperature, and transportation distance.

5. Branding: Select packaging that reflects your visual identity.

6. Material requirements: Review recycling, sourcing, and disposal considerations.

7. Order volume: Choose a packaging format that works with your fulfillment process.

If you need a more customized packaging solution, you can request a custom packaging order from Arka .

Final Thoughts

Packaging symbols help communicate information about materials, safety, handling, transportation, and disposal.

From recycling codes and plastic identification numbers to fragile and keep-dry symbols, each mark has a specific purpose. However, the meaning and legal requirements of a symbol vary by market, product, and relevant standards.

Businesses should verify each symbol before use, avoid unsupported environmental claims, and provide written instructions when a symbol alone is insufficient.

Effective packaging combines clear communication with suitable materials, product protection, and a practical customer experience.
