ToggleWhat are packaging symbols

Types of packaging symbols
- Environmental and recycling symbols
These show if a package can be reused, recycled, or safely thrown away. - Handling and storage symbols
These tell workers how to carry, stack, or store the product without causing damage. - Transit or shipping symbols
These are used for customs, freight, and transport safety—especially for exports. - Food packaging symbols
These explain if a package is food-safe, microwave-safe, or has allergen risks. - Certification and compliance symbols
These show the product or packaging meets safety or legal standards, like CE or UL.
Environmental and recycling symbols on packaging boxes
These symbols help people understand how to reuse, recycle, or dispose of your packaging. They’re especially important if you care about sustainability — or if your customers do.
Let’s look at the most common ones:
Mobius Loop
This triangle made of three arrows is the universal sign for recycling. It means the material is recyclable. Sometimes there’s a number inside or a percentage below it, which tells you what type of material it is and how much has been recycled.
Biodegradable, Compostable, and Recyclable Icons
These symbols can look different depending on your country. Some show a leaf, a sprouting plant, or just say “100% compostable.” They help customers know if the packaging can break down naturally or be reused.
Ever see a triangle with a number from 1 to 7 inside it? That’s a plastic resin code. It tells recycling centers what kind of plastic your packaging uses—like PET (#1) or HDPE (#2). Not all plastics are recyclable in all areas, so this symbol helps sort things correctly.
The Green Dot
This looks like two arrows chasing each other in a circle. It doesn’t mean the item is recyclable. It means the manufacturer paid into a recycling or recovery program (mainly used in Europe). It’s often confused with the Mobius Loop.
This symbol is usually a box with arrows or a line of curved waves. It tells users the box is made from corrugated cardboard and can be recycled. It’s commonly used for shipping cartons.
Handling and storage symbols
Here are the most common ones you should know:
Fragile (wine glass icon)
This means the contents inside can break easily. It tells handlers to be gentle—don’t toss or drop the box.
Keep Dry (umbrella with raindrops)
This icon warns that water can damage the product. Use it for electronics, paper goods, or anything sensitive to moisture.
This Side Up (two arrows pointing up)
Tells workers how to position the box correctly. It prevents spills or damage caused by tilting or flipping.
Temperature-Sensitive and Light-Sensitive
Some packages include icons showing a thermometer or a sun. These mean the contents must be kept at a certain temperature or away from sunlight—common for food, batteries, or cosmetics.
Shelf Life and Expiration Date Symbols
These symbols are used on items with a limited use period. You may see a little hourglass or an open jar icon with a number like “12M” (which means good for 12 months after opening).
Handle with Care
This symbol often shows two hands holding a box. It’s a general reminder to move the box gently.
Do Not Open with a Knife
This shows a knife with a slash through it. It’s used when the item inside is right under the lid—like soft goods or vacuum-sealed products. It warns people to open carefully to avoid cutting the product.
Do Not Drop
This icon warns that even a short fall could cause damage. You’ll see this on electronics, glassware, and other delicate products.
Stacking Height Limit
This symbol shows boxes stacked with a number next to them—like “Max. 5.” It helps prevent collapsing stacks in warehouses.
Do Not Stack
Shows a box with a cross over a second stacked box. It means stacking could damage the contents—very important for delicate items like jewelry boxes.
Maximum Load Weight
Usually displayed as a weight icon or a number next to a box. Here are 5 typical examples and matching cardboard types:
- 10 kg → single-wall kraft box
- 15 kg → double-wall box
- 20 kg → heavy-duty double wall
- 25 kg → triple-wall corrugated
- 30+ kg → custom-reinforced export cartons
Some packages simply show the actual weight (like “12kg”). This helps handlers avoid injury or use the right equipment.
Transit packaging symbols
If your product is considered hazardous (like chemicals, batteries, or flammable liquids), it needs special labeling. The United Nations (UN) has a system for this.
- UN 4G – Fiberboard box for dangerous goods
- UN 1H2 – Plastic drum, open head
- UN 3H1 – Plastic jerrican, closed head
- UN 1A1 – Steel drum, tight head
These codes are part of international transport laws. If you’re shipping lithium batteries, for example, you’ll need UN-compliant packaging with correct markings.
International Maritime and Air Freight Symbols
These include icons like an airplane, a cargo ship, or “IATA” (International Air Transport Association). They’re used to show a package is certified for air or sea freight. If your product can’t fly (due to pressure or battery risk), that must be labeled clearly.
Country of Origin and Customs Symbols
These symbols help goods pass through customs faster. You might see:
- “Made in China,” “Made in USA”
- Barcode symbols for HS code and customs declaration
- Export certification marks (used in some regions)
Food packaging symbols
Food-Safe Contact Symbol (glass and fork)
This symbol looks like a wine glass next to a fork. It means the packaging is safe to touch food directly. You’ll often see it on plastic containers, paper wrappers, or aluminum trays.
Use-By Date vs. Best-Before Date
These two labels are not the same:
- Use-by date means the food should not be eaten after that day. It’s about safety.
- Best-before date means the food might lose taste or texture after that day, but it’s still safe to eat.
Allergen Warning Symbols
Some packages show icons for nuts, gluten, or soy, usually with a slash if they’re not included. These are important for people with allergies. In some countries, it’s required by law to show them clearly.
Microwave-Safe and Freezer-Safe Icons
These symbols tell people if the packaging can go in the microwave or freezer:
- A microwave icon usually shows wavy lines
- A snowflake icon means the packaging can be frozen without damage
You may also see a “do not microwave” symbol if the material isn’t heat-safe.
Certification and compliance symbols
Let’s break down the most common ones:
CE Marking (European Conformity)
This symbol is used in the European Union. It means the product meets EU safety, health, and environmental rules. If you’re selling packaging or products in Europe, this mark is often required—especially for electronics and toys.
RoHS (Restriction of Hazardous Substances)
This symbol means the product follows EU rules that limit harmful substances like lead, mercury, and cadmium. It’s mostly used for electronic items but can also apply to packaging with coatings, wires, or adhesives.
UL (Underwriters Laboratories)
This symbol is mainly used in the United States and Canada. It means the product has been tested for fire, shock, and safety risks. UL is common on electronics, battery packs, and other items that might overheat or catch fire.
FDA and USDA Symbols
If your packaging touches food in the United States, it may need to be approved by the FDA (Food and Drug Administration) or USDA (U.S. Department of Agriculture). These marks show the material is safe for direct contact with food, like paper trays or plastic liners.
FSC (Forest Stewardship Council)
The FSC logo shows that the paper or cardboard comes from responsibly managed forests. It’s popular on eco-friendly packaging and is a great way to show your sustainability efforts.
Accessibility and inclusive use symbols
Here are a few important ones:
Easy-Open Packaging Icon
This symbol usually shows a hand opening a box or peeling a corner. It means the package is easy to open—no scissors or sharp tools needed. It’s useful for seniors, kids, or people with limited hand strength.
Braille or Tactile Symbols
Some packages include braille dots or raised markings. These help people who are blind or visually impaired identify what’s inside. You’ll often find this on medicine boxes or personal care items.
Child-Safety or Age Warning Symbols
You might see a “0–3” icon with a slash through it. That means the item isn’t safe for children under 3 years old (due to choking risks or small parts). There are also lock or latch symbols that show child-proof features.
How to choose and use packaging symbols for your products
- What type of product are you packaging? (Food, electronics, fragile goods?)
- Where will it be sold or shipped? (Local or international?)
- Are there any laws or industry rules you need to follow?
Once you know those answers, you can select the symbols that fit your needs. For example, a food container may need a food-safe symbol, a “use-by” date, and a recycling icon. An export carton might need UN codes, a stack limit, and a “this side up” mark.
You’ll also want to make sure your symbols are placed clearly, sized properly, and not overcrowded.
- ❌ Using unofficial or made-up icons
- ❌ Putting too many symbols in a small space
- ❌ Skipping important safety or compliance marks
- ❌ Making symbols too small to read
- ❌ Printing symbols in the wrong location (like under tape or flaps)
- ❌ Ignoring regional label laws (EU vs. US vs. Asia)
