The Benefits of Using Carbon Black Pigment in Food Packaging
Extended Shelf Life
Food packaging plays a vital role in extending the shelf life of perishable products. Carbon black pigment aids in this process by acting as a barrier against oxygen and moisture. These pigments possess high gas and water vapor resistance, preventing the entry of external contaminants that can compromise the quality and safety of packaged food. By creating a protective environment, carbon black pigments help maintain freshness, preserve flavors, and prevent microbial growth, ultimately prolonging the shelf life of food products.
Preservation of Nutritional Value
The nutritional value of food can significantly degrade when exposed to environmental factors such as light, heat, and oxygen. Carbon black pigment, with its light-blocking and oxygen-resistant properties, safeguards the delicate nutrients within packaged food. This preservation of nutritional value is crucial for maintaining the health benefits of the product, ensuring that consumers receive the intended nutrients and enjoy a nutritious diet.
Increased Safety
Food safety is a primary concern for both consumers and manufacturers. Carbon black pigments are widely recognized for their inert and non-toxic nature, making them a safe choice for food packaging. These pigments have a long history of use in various applications, including food contact materials, and have undergone extensive testing to ensure their safety. By incorporating carbon black pigment into packaging materials, manufacturers can meet stringent food safety regulations and provide consumers with peace of mind regarding the integrity of the products they consume.
Sustainability
In recent years, sustainability has gained significant importance in the packaging industry. Carbon black pigments offer advantages in this aspect as well. Firstly, their low density contributes to lightweight packaging, reducing material usage and transportation costs. Additionally, carbon black pigments are derived from carbon sources, which can be renewable or recycled, reducing dependence on non-renewable resources. By incorporating sustainable pigments into food packaging, companies can make strides toward reducing their environmental footprint and meeting consumer demands for eco-friendly solutions.
N type carbon black
N-type carbon black refers to carbon black produced under normal processes. This type of carbon black has different wear resistance and strength properties and is suitable for various application scenarios. N-type carbon black is divided into multiple grades according to different particle sizes, such as N220, N330, N550 and N660. The smaller the particle size, the better the reinforcing effect of carbon black, but it may also lead to poorer processability of rubber. Therefore, selecting the appropriate N-type carbon black grade is critical to balancing product performance and processability.
High structure carbon black
High structure carbon black refers to carbon blacks with higher aggregate sizes, which generally have higher porosity and surface area. High-structure carbon blacks are excellent at enhancing the tear strength, elasticity and electrical conductivity of rubber, so they are often used in applications requiring these properties, such as high-performance tires and some special industrial rubber products.
Ires and Industrial Rubber Products
Black Carbon is added to rubber as both a filler and as a strengthening or reinforcing agent. For various types of tires, it is used in innerliners, carcasses, sidewalls and treads utilizing different types based on specific performance requirements.It is also used in many molded and extruded industrial rubber products, such as belts, hoses, gaskets, diaphragms, vibration isolation devices, bushings, air springs, chassis bumpers, and multiple types of pads, boots, wiper blades, fascia, conveyor wheels, and grommets.
Plastics
Carbon blacks are now widely used for conductive packaging, films, fibers, moldings, pipes and semi-conductive cable compounds in products such as refuse sacks, industrial bags, photographic containers, agriculture mulch film, stretch wrap, and thermoplastic molding applications for automotive, electrical/electronics, household appliances and blow-molded containers.
High Performance Coatings
Pigment Carbon blacks provide pigmentation, conductivity, and UV protection for a number of coating applications including automotive (primer basecoats and clearcoats), marine, aerospace, decorative, wood, and industrial coatings.
Toners and Printing Inks
Pigment Carbon blacks enhance formulations and deliver broad flexibility in meeting specific color requirements.
Properties of Carbon Black N339
Structure and Aggregate Size
Properties such as particle size distribution and aggregate size could perfectly be measured using transmission electron microscopy (TEM). In addition to this, dibutyl phthalate absorption is widely applied to determine the morphology and structure of carbon black in comparison to those prepared using different methods. Aggregation of carbon black can be classified into four basic groups namely, branched, linear ellipsoidal and spheroidal. It should be noted that carbon black has a portion of these four types combined with the lower grade having more ellipsoidal and spheroidal aggregates, whereas the high-quality grade contains mostly branched aggregates. Surprisingly, the branched and linear aggregates could potentially be broken down to some extent within an intense mixing attempt.
Particle Size Distribution
The particle size of carbon blacks could be determined and measured so accurately using transmission electron microscopy along with iodine number and nitrogen surface area which in turn provide indications of relative particle size. Typically, the particle sizes range from 10 nm for furnace processing grains up 100 nm on average. In fact, the distribution of particle size turns out to play a key factor in the performance and properties of carbon blacks. As an instance to this, a wider particle size distribution could possess a lower surface area leading to a less viscous product with applications in coatings, plastics and poor hysteresis properties in rubbers.
Pore Size Distribution and Porosity
The morphology of carbon black crystals is characterized using electron microscopy with an accuracy of less than 2 nanometers in diameter. Measuring porosity in carbon black, however, is carried out by gas absorption and density determination tests. The most common adsorption method is called BET which is based on using nitrogen gas to determine the pore size of the crystals.
Surface Activity of Carbon Blacks
Regarding the surface roughness and energetic surface structure of commercial and experimental carbon black particles, the surface activity of carbon blacks with different aggregate structures and particle sizes is precisely investigated. Particularly, the energetic surface structure is determined by a function called site energy distribution basically evaluated by the gas absorption isotherms of ethene. The fraction of the surface of carbon black crystals mainly depends on the particle size, grade and process through which the crystals are prepared. In the case of furnace carbon black, the fraction of the sites with higher energy drops considerably with particle size and fades away during graphitization process. This is an indication of carbon black reinforcing potential being closely related to the rate of highly energetic sites to be quantified by gas absorption techniques.
How to Choose Carbon Black N339

Process of Carbon Black N339
Feedstock Preparation
The chosen hydrocarbon feedstock is heated and vaporised to prepare it for carbon black production. This can involve processes such as distillation or cracking.
Carbon Black Formation
The vaporised hydrocarbon feedstock is introduced into a reactor or combustion chamber, undergoing controlled combustion or thermal cracking at high temperatures (around 1,500 to 2,000 degrees Celsius). This process breaks down the hydrocarbon molecules into smaller carbon units.
Particle Formation
As the hydrocarbon molecules break down, the carbon atoms aggregate and form tiny particles. These particles are predominantly carbon, with sizes ranging from 10 to 500 nanometers.
Separation
The carbon black particles are separated from the process gases. This is achieved using a combination of quenching, filtration, and centrifugation processes. The separated carbon black is collected as a powder.
Post-Treatment
The collected carbon black powder may undergo post-treatment processes to modify its properties for specific applications. Post-treatment can involve surface oxidation, pelletisation, or other treatments to enhance dispersibility, improve color, or impart specific characteristics to the carbon black.
Cleaning fluid
For more stubborn carbon black stains, you can use appropriate cleaning fluid. Choose a non-abrasive cleaner, apply it to the carbon black stain, and wipe with a damp cloth. When cleaning, be careful not to use excessive force to avoid damaging the surface.
Rubber cleaning
For carbon black stains in rubber products, special rubber cleaners can be used. Apply cleaner to the carbon black stain, follow instructions, and rinse with clean water.
Plastic cleaning
For carbon black stains in plastic products, you can try using bleach or alcohol to wipe them. Wipe the carbon black stain first with a damp cloth, then wipe gently with diluted bleach or alcohol, and finally rinse with clean water.
Use protective measures
When coming into contact with carbon black, try to take appropriate protective measures, such as wearing gloves, long-sleeved clothing, etc. This helps reduce the chance of carbon black staining your skin and clothing.
Treat Stains Quickly
Once carbon black stains develop, they should be treated as quickly as possible and not allowed to dry, making the cleaning process more difficult.
