If the choice of materials is crucial for the insulation performance of a cooler bag, then the printing of the cooler bag is essential for its visual appeal. How to provide customers with good printing choices is a reflection of a cooler bag manufacturer’s professionalism, directly impacting the success of brand promotion and marketing activities. Here, as a professional cooler bag factory, we will introduce two commonly used printing methods.
Screen Printing
Screen printing belongs to stencil printing, where ink is squeezed through mesh openings onto the substrate by a squeegee, reproducing the desired image or text. The current automated batch screen printing technology allows for large-scale printing operations.
Features
Versatile Substrates
Screen printing can be applied to flat or curved, rigid or flexible, large or small objects, making it suitable for a wide range of items, especially those prone to breakage or deformation.
Strong 3D Effect
Screen printing produces realistic reproductions with a strong 3D effect, surpassing offset printing in color rendering. However, fine details may be limited in reproduction.
Excellent Lightfastness
By adding light-resistant and fluorescent pigments to the ink, screen-printed images can maintain a permanent gloss unaffected by temperature and sunlight, even glowing in the dark. This makes screen-printed products suitable for outdoor advertising and signage, providing unique advantages for brand promotion.
Large Format
In terms of printing area, screen printing far exceeds methods like offset and gravure due to fewer mechanical limitations, with maximum dimensions reaching 3m x 4m or larger.
Variety of Inks
Screen printing inks, collectively known as printing materials, can include water-based, oil-based, solvent-based, and other types. Technological advancements have expanded the range of inks beyond traditional definitions, encompassing substances like paste and powder.
Cost-Effective
Screen printing inks are suitable for large-scale printing, offering lower costs compared to other printing technologies, making it cost-effective.
Dip Molding
Dip molding utilizes the variable state characteristics of thermoplastic polymers, which exhibit flowability under specific conditions and return to a solid state at room temperature. The process involves placing raw materials into specific molds, shaping them as required in their flowable state, and then curing them on a baking platform.
Features
The raw material PVC used in dip molding is a colorless, transparent thermoplastic with excellent chemical stability, weather resistance, and wear resistance. However, it comes with higher costs, requiring mold development.
Applications of Dip Molding
Widely applied in the decoration of various items such as trademark nameplates, cards, daily hardware products, tourist memorabilia, exquisite handicrafts, and high-quality book covers. It is also a commonly used logo printing technology for cooler bag production, resembling PVC silicone products used for labels on bags, backpacks, apparel, and more.
These are the most commonly used printing technologies for cooler bags, ensuring printing costs and effects while not compromising the insulation performance of the bag. If you have other printing requirements, feel free to contact us for your cooler bag customized solutions.
