Blow Molding Masterbatch Solutions

For close to two decades now, we have committed ourselves to the research, development, and production of Color Masterbatch and Functional Masterbatch products.

Our technical staff is well versed in U.S. experience and has had many years of serving customers in the areas of packaging, chemical shipping, pharmaceutical packaging, and household/personal care sectors.

Thus far, we have created numerous color combinations, especially those intended for the blow molding industry.

They include the following application fields:

  • HDPE Blow Molding
  • PP Blow Molding
  • PET Blow Molding
  • Pharmaceutical Packaging
  • Chemical Packaging

Three Typical Applications in the Blow Molding Industry

Chemical Drums

Chemical packaging is one of the most difficult challenges faced by masterbatch in the field of blow molding technology.

This is because such products are exposed to acids, alkalis, salts, and various organic solvents, where the usual colorants tend to fade away, migrate, or chalk out on the surface.

To overcome this problem, we use chemically stable pigment system along with high dispersion technology to make special masterbatches. Our masterbatches not only remain stable but also provide excellent color stability and visual uniformity even when exposed to corrosive media like nitric and hydrochloric acids.

Household & Personal Care Bottles

Products including shampoo bottles, laundry detergent bottles, and disinfectant bottles are now placing greater importance on the branding identity and branding recognition.

Not only is accurate color important for the consumers, but the consumers must be assured that there is no chance of any color discrepancy or discoloration during long periods of display on shelves.

Our company has been able to create a vast database of colors that can be matched easily using Pantone colors. The batch-to-batch management process ensures that consistency is maintained in each batch produced by our company.

Pharmaceutical Bottles

Requirements for pharmaceutical packaging go beyond just being visually attractive. High safety and long-term stability of the product is of crucial importance.

A large number of pharmaceutical packaging materials are supposed to have long-term storage properties as well as meet a lot of strict requirements from regulations.

From our practical experience, the two most important factors for the application of pharmaceutical bottles are low extractables and low migration properties.

Therefore, we pay much attention to the usage of high-purity pigments and highly stable carrier resin systems.

Why Are More and More Blow Molding Customers Choosing Us?

When it comes to launching a new product or refreshing a hero line,te right packaging partner makes all the difference.Here’s why brands around the world choose to work with us.

Excellent Chemical Resistance Properties

When dealing with the packaging of chemicals, color retention proves much more critical than the color appearance at the beginning. In cases like those of chemical drums and agrochemical packaging, the right pigment system is chosen in line with the particular stored media with emphasis placed on the ability to withstand both acid, base, and chemically aggressive conditions.

Excellent Colorfastness

A lot of masterbatch materials might look very attractive upon production, but tend to start fading through transportation, warehousing, and/or open-air exposure. Color should not only be provided, but sustained over time. Lightfast and thermal stable pigments are preferred by us as they minimize color fading risks during transportation, warehousing, and usage stages.

Quality Assurance That Is Consistent

One of the biggest concerns for blow molded parts producers is that they have varying products each time. Through our ISO certified quality management process and stringent inspection procedures, we ensure consistency in every aspect, from start to finish, of production processes.

Fast samples speed

Our prototyping speed is among the best in the industry, with samples ready for clients in as little as 1–3 working days. We help clients quickly capture the market.

Short delivery lead time

To better serve our customers, we can shorten the lead time for urgent orders to 3–5 working days.

Professional pre-sales, in-sales, and after-sales services

Our sales team possesses over a decade of industry experience, enabling them to quickly identify your actual needs and accurately convey them to our internal teams. Should any issues arise, our after-sales team will step in immediately to troubleshoot the problem alongside the customer.

Excellent Dispersion Effect

With the experience gained over almost twenty years of industrial practice, we are aware that among all products, chemical drums, drug bottles, and high-volume packing boxes will be those most prone to problems associated with dispersion. We have an excellent dispersion processing system combined with a strict system of testing our raw materials, which ensures an evenly colored product despite a low amount of added materials.

Extractables and Migration Systems

Problems with regard to extractables and migration tend to be discovered after the first day.
The presence of surface tackiness, label de-lamination, and poor print adhesion is often linked to problems concerning extractables and migration. Our formulation process focuses on low migration and low extractables systems, which makes our masterbatches ideal for pharmaceutical bottles and household product packages.

Development of Custom Formulations

It is important to understand that what many customers really require is not just a color masterbatch that is ready for purchase.
No, what they require is an appropriate masterbatch formulation that would be tailored to their particular product.
We have services of Pantone color matching, sample-to-match color development, as well as unique custom color development. We can also develop a masterbatch formulation including functional requirements such as weatherability and chemical resistance.

Case Study of Film Masterbatch

A Listed Pharmaceutical Packaging Company in Jiangsu Province

The customer’s pharmaceutical bottles of the customer have been sold to European and American customers on a consistent basis over time, which creates very high demands with regard to the resistance to migration and stability of such products. The unique masterbatch for blue with low extractables was created and validated by the customer successfully.

Chemical Raw Material Storage Drum Project for an International Brand

However, there was an exposure of the products of the client to the nitric acid medium, and the dyeing system showed signs of fading. With the optimization of the formula, we were able to increase the nitric acid corrosion protection cycle without any deterioration in the color, improving the competitiveness of the products in the market.
