COF Testing in Product Packaging

Apr 21, 2021 | Blog Posts, COF testing

The coefficient of friction (COF) can be an important subject in the world of packaging and is definitely a significant home of all materials that run on packaging lines. By definition, COF can be a measure of slip, or how a single surface moves across a further. The importance is in how a substrate moves by means of and across print stations, conveyor belts, onto the container, or released from a mandrel or loading soon after processing. Films with COF values greater than 0.5 are regarded nonslip. COF is normally specified for a provided procedure and adjusted by the printer with inks or varnishes as necessary.

Depending on the packaging application, a high or low COF could possibly be preferred. When a material traction feed system is employed, or when the application calls for an easy-to-hold container exactly where a slippery surface could be tough to manage, a higher COF will be favorable. On the contrary, in situations exactly where the material is getting pulled more than a forming collar, for instance with vertical form, fill and seal (VFFS) equipment, a low COF is regarded to be favorable. Likewise, if shrink sleeves are getting applied through higher speed gear, then a low COF normally performs greatest.

Controlling COF gives processors the capacity to optimize overall performance and stay clear of troubles in forming, transporting, and storing packages. Getting the COF ideal is mainly a course of action of qualifying a packaging item after which supplying this product at a constant COF specification based on an offered instrument and testing procedure. It is actually essential to keep in mind that quite a few converting variables cause COF to vary. For instance, this home is sensitive to application viscosity, coating weight, drying situations, and environmental humidity. So, running to proven standards guarantees low waste and fewer field issues and returns.

 

Importance of Suitable COF Testing

The flexible packaging film ought to be of appropriate coefficient of friction otherwise adverse effects might be triggered during the operation. To become precise, if the coefficient of friction is also high, it will call for a greater pulling force to unwind the roll from the plastic film. Consequently, the production efficiency is going to be compromised, and also worse the film can be deformed right after becoming stretched excessively. On the other hand, with the coefficient of friction is as well low, the films may well slip or fall off from the roll, which could bring about the suspension of production and unnecessary production expense. Thus it truly is fairly important to the companies and customers of versatile packaging film to handle its coefficient of friction and select appropriate packaging components by way of COF tests.

 

Ways to Measure Coefficient of Friction of Plastic Films?

Coefficient of friction COF testing is completed in poly film packing sector to assess their stacking capacity. Plastic film has quite low friction as a consequence of which you can find ample possibilities of slippage. The COF testing is accomplished to ascertain the easiness with which two facades when placed in make contact with each other are able to slide on 1 another. The coefficient of friction testing aids to decide two values, i.e. Static friction and Kinetic friction. Static friction contributes to determining the energy expected to begin the motion in between two surfaces even though the kinetic friction contributes to figuring out the resistance to sliding once both the facades are in relative motion.
