IP Ratings Explained for Packaging Equipment

When you hear terms like “water-resistant” or “dust-proof,” what comes to mind? These phrases are commonly used by manufacturers to describe the durability of their products, from cameras to packaging machinery. However, interpretations of these terms can vary, leading to confusion. To standardize these definitions, the European Committee for Electro Technical Standardization introduced Ingress Protection (IP) Ratings under the IEC 60529 standard.

If you’re considering purchasing packaging equipment, it’s crucial to understand these ratings thoroughly. To help you navigate this process, Mentpack’s sales team is ready to listen to your needs and create tailored solutions that align with your operational requirements.


What is an IP Rating?

An IP Rating indicates the level of protection a device offers against the intrusion of solid objects and liquids. It typically consists of two numbers: the first represents protection against solids, and the second against liquids. An optional third letter may provide additional information, though it’s often omitted.


How to Choose the Right IP Rating

The appropriate IP Rating for your packaging equipment depends on your specific manufacturing environment, product properties, and cleaning procedures. For most standard environments, IP65 or IP66 ratings are sufficient, offering robust protection against dust and water.

However, it’s important to note that not all components of a packaging system may have the same IP Rating. For example, attached printers might require additional protective covers during cleaning.

Consult with your internal experts and review the specifications of each component to determine the best IP Rating for your needs. And remember, Mentpack’s sales team is here to help you navigate these decisions and create solutions tailored to your requirements. Reach out today to ensure your packaging equipment meets your operational demands.

Protection Against Solids

The first digit in an IP Rating ranges from 0 (no protection) to 6 (complete protection against dust and other solid particles).

Protection Against Liquids

The second digit ranges from 0 (no protection) to 9K (protection against high-pressure, high-temperature water jets).

Additional Protections

An optional letter can describe other protective features, though this is rarely used.


Why Are IP Ratings Important?

Manufacturers seeking an IP Rating for their products must have them tested by an independent, certified company. This certification ensures that the product meets specific standards for protection against solids and liquids. For customers, this means greater confidence in the product’s durability and suitability for their needs.

IP Ratings also help users understand the equipment’s limitations, enabling safer operation and proper maintenance. This reduces the risk of injury or damage to the equipment.


IP Rating Reference Chart

First Digit: Solid Particle Protection

LevelEffective AgainstDescription
0No protection against contact or ingress of objects.
1>50 mmProtects against large surfaces like the back of a hand.
2>12.55 mmProtects against fingers or similar objects.
3>2.5 mmProtects against tools, thick wires, etc.
4>1 mmProtects against most wires, slender screws, etc.
5Dust protectedDust ingress is limited and won’t interfere with operation.
6Dust-tightComplete protection against dust.

Second Digit: Liquid Ingress Protection

LevelProtection AgainstDescription
0NoneNo protection against liquids.
1Dripping waterProtects against vertically falling drops.

IP Ratings in Packaging Equipment

Most packaging machines feature IP-rated electrical and pneumatic enclosures, such as circuit boxes or cabinets. These protect internal components from dust and liquids, which can cause malfunctions or safety hazards. Common IP Ratings for packaging equipment include:

  • IP65: Dust-tight and protected against low-pressure water jets.
  • IP66: Dust-tight and protected against strong water jets.
  • IP67: Dust-tight and protected against temporary immersion.
  • IP68: Dust-tight and protected against continuous immersion.

Why IP Ratings Matter in Packaging Equipment Selection

Choosing the right IP Rating for your packaging equipment depends on your operational environment. Here’s how to decide:

Dusty Environments

In industries like snack or coffee packaging, dust can damage exposed components. An IP Rating of 5-6 for solids is recommended, while liquid protection may be less critical.

Wet Environments

For food packaging involving cheese, meat, or sticky candy, regular cleaning is essential. A liquid IP Rating of 5-8 is ideal, while solid protection may be less important.

Combined Environments

For settings that are both dusty and require frequent washdowns, consider an IP Rating of 55-68. This ensures protection against dust and water ingress, including immersion.
