How to Make Mylar Bag Step by Step

#1 Raw Materials For Making Mylar Bag
At Rainbow Pouch, everything starts with the raw materials, as they form the foundation of our high-quality packaging solutions. Just like the food that nourishes the body, the quality of our raw materials ensures the strength and integrity of the final product. The primary materials used for our Mylar bags and pouches consist of various films, which undergo a careful and precise manufacturing process.
Our top priority is to produce exceptional bags by laminating them with high-performance films. These films are carefully selected for their superior properties and are processed with three or four layers of lamination, sourced from reputable blown film manufacturers. We prioritize working with trusted suppliers to ensure the materials meet the strictest standards.
The lamination process is tailored to the specific needs of our clients, taking into account the bag’s size and material to determine the ideal film type. Each film undergoes thorough quality checks to ensure it meets our rigorous criteria. This lamination process is used for various products, including zipper bags, Mylar bags, and other types of food packaging bags, ensuring they maintain the highest quality and functionality.

#2Copperplate for making packaging bags and Pouches
As we have long-term experience in copperplate engraving, our manufacturing wins the trust of Buyers.
After lamination, the general composite bags are engraved by copper plate printing processes. Then processed with the perfect size and pattern of the plate according to the customer’s needs. As once copper plate engraving is completed, its size of it can no longer be modified. So, we provide the exact size plate of copper according to the customized bag. The engraving procedure satisfies buyers. That’s why our eye-pleasing bags and pouches are preferred. We use different methods for engraving like the gravure process.
- We confirm that the pattern and size are correct so that re-plating may be avoided. It declines our loss ratio and ensures on-time delivery. We ensure an uninterrupted supply of products.

#3 Printing during the Packaging of Bags and Pouches Production Process
Rainbow Pouch boasts a highly skilled team and dedicated workers who are committed to delivering the best custom Mylar bags. Equipped with state-of-the-art machinery and skilled employees, we produce bags with exceptional designs and high-quality prints that meet our customers’ exact specifications. Our advanced printing technology uses multi-layered film to ensure that the patterns stay vibrant and resistant to fading, even after the bags are assembled. This specialized printing technique ensures the colors remain intact, protecting the design from the elements.
Our printing process also offers excellent protection against factors such as temperature, humidity, and other environmental conditions. This ensures that your product stays fresh and retains its quality, preserving its aroma and appeal.
Another advantage of our custom Mylar bags is their ability to catch customers’ attention with striking designs. At Rainbow Pouch, we don’t just sell packaging—we care about your products and ensure that our packaging helps your brand shine in the market.

#4 Printing during the Packaging of Bags and Pouches Production Process
The production of our custom Mylar bags follows a meticulous, step-by-step process. While this process allows us to create the highest quality bags, it also presents some challenges, especially when it comes to customizing packaging to meet specific client needs.
Our Mylar bags are made from various materials, with multiple layers of film laminated together. This lamination is achieved through a composite process, which ensures durability and functionality. We utilize a solvent-free compounding machine that eliminates the need for adhesives, reducing composite costs by almost 30%. This technology is not only cost-efficient but also protects the original equipment and is more environmentally friendly, making it an ideal solution for producing high-quality bags.
These advancements in our manufacturing process elevate the overall quality of our plastic packaging bags, ensuring they meet the highest standards of performance. At Rainbow Pouch, we offer a wide range of solutions for bag manufacturing, tailored to meet our clients’ specific needs.
