2 Foil Materials

This foil material features a reinforced structure developed specifically for cat litter packaging applications. The PA15/LDPE construction offers excellent strength, durability, and barrier performance, making it well suited for heavy filling and long term storage. The graphic design is shown below.

Let’s first get a further understanding on each substrate layer material.

PA15, or Polyamide (Nylon), is a high performance material widely used in flexible packaging. It provides excellent puncture resistance, tensile strength, and durability, making it ideal for heavy filling and products like cat litter that require reliable handling and transport.

When combined with layers such as LDPE, PA enhances bag stiffness, maintains standing performance, and improves barrier properties against moisture and oxygen. This ensures the package remains strong, stable, and protective throughout storage and use.

LDPE is a versatile, flexible polymer widely used in packaging films and bags. It offers excellent moisture barrier properties, chemical resistance, and flexibility, making it ideal for products that require secure sealing and easy handling.

LDPE also provides good impact resistance and heat sealability, ensuring reliable closure and maintaining product freshness. Its lightweight yet durable nature helps create cost-effective packaging while supporting consistent performance in daily use.

3 Properties and Quality Assurance

3.1 Exquisite print quality

The artwork is achieved in gravure printing on our rotogravure print press which can print up to maximum 10 colors. With advanced print techniques and print defects inspection system, we are now outputing fantastic print effects for the customers’ artwork.

At our manufacturing facility, we ensure outstanding color accuracy and consistency in every production run. Whether it’s a new project or a repeat order, our advanced printing technology and strict quality controls deliver precise, vibrant results that faithfully bring your brand to life.

a.  Color Analyzer

Our advanced color analyzer, powered by the X-Rite eXact Advanced, ensures unparalleled precision in every print. It goes beyond simple validation, providing full-spectrum color control for consistent, vibrant results.

• Versatile Measurement: Accurately validates CMYK and spot colors.

• Four M Modes: Captures complete spectral reflectance for detailed analysis.

• Ink Precision: Measures ink concentrations with exceptional accuracy.

• Substrate Consistency: Detects color differences on white and black surfaces to ensure reliability across materials.

With these capabilities, the eXact Advanced allows us to consistently deliver the highest standards of quality, consistency, and color fidelity for every project.

b. Pantone Color Code

The Pantone color guide is invaluable for accurately specifying colors for both our printing service and our customers, especially for large areas printed in a single Pantone shade. However, factors such as the printer, paper substrate, and environmental conditions can affect color accuracy when printed on physical media.

To ensure precise results, we confirm the Pantone Color Code with our customers during the artwork design stage before production begins, ensuring the final print matches the intended color.

c. Physical Printed On Photo Paper

Digital files such as JPG, PDF, PSD, or AI cannot be used as a definitive guide for printed colors, as they display colors through electronic screens. Different devices and manufacturer settings can alter the appearance, making on-screen colors unreliable.

Artwork can only serve as an accurate reference when printed on physical substrate, with photo paper being the most commonly used medium to evaluate true color representation.

Serious quality control measures have been taken in our manufacturing plant, to ensure each order is finished meeting the requirements of particular customers. With more than ten years of working experience in this field, we finalize this QC manual standard, to make sure each order is produced following the correct procedure.

Here, please allow us to guide you further into our QC system.

4.1 Manufacturing Traceback

We implement a strict recording system to document all manufacturing details, including environmental conditions, process parameters, and production facility status. This comprehensive traceability system allows us to quickly identify and review any stage of production whenever an issue arises.

4.2 QC Test Report Against Each Order

There will be a QC test report issued against each order produced, with the core items evaluated in it.  It is highly appreciated by our customers.

4.3 Print Inspection

In our manufacturing plant, the print inspection is always taken and done in a serious way, as we will never allow the customer artwork to be achieved in a way that deteriorate their business. On our gravure print press, there is in-line inspection system which can eliminate more than 98% of the defects in the printing process.

You may check how it works on our control panel.

 

There is also a supplementary off-line inspection equipment, to allow us to do the print inspection again whenever it seems necessary.

We are now producing cat litter bags against customer artwork, and we surely love to support the startup and market-testing period for our customers. We will accept a minimum order quantity of 10,000 bags printed against customer artwork design.

4.4 Airtight Property Test

The finished coffee bag should be completely airtight, to get the products well-protected from oxygen and moisture in the environment. We perform the airtight property test against each order with the device as below.

In actual operation, we will pick up 1 bag every 1,000 pcs, and perform the test following the procedure in our QC manual.

4.5 Drop Test

Drop test should be considered as a very reliable way to check if the coffee bag strength is enough to meet the various conditions, as it copies the way when the products falls off the good shelves, and the finished bag will suffer great sudden shock. In our daily QC work, We perform drop test against each order, of course, the standard for this drop test should be decided against customer needs.

Here, we are going to drop the filled coffee bag from 1.6m high, for 3 times.

You are advised to watch the video below, for a further understanding.

After 3 drops for each bag, none of them breaks, all are fine and dandy.

4.6 Hard Sudden Strikes on inflated  bags

Hard sudden strikes should be taken as a more fierce test method than drop test, as it causes much higher force on inflated packages.

Let’s watch the video to understand how we perform this test in our manufacturing plant.

4.7 Anti-Pressure Test

Pressure-resistance test is another effective method to decide if the final package will serve as great protection for the products, especially liquid products, like household detergent liquids, and windshield washer fluids. For coffee bags, we will perform the anti-pressure test in our daily QC work, to ensure each order is finished with great mechanical strength.

The leakage or breakage of the coffee bag will surely be a disaster, either for the distributor or the manufacturer.  We will never expect this thing happens in our customer’s business.

Sometimes, for easier and fast operation, we may just get one person to stand on the well-sealed and inflated coffee bag, to check if there is any burst of them.

4.8 Laboratory Tests

Laboratory tests are essential to keep us updated with the intrinsic properties of the foil materials which are not visible to the human eyes. It is crucial for gaining a thorough understanding of the data about the production of our bags. The craftsmanship can be improved bit by bit to pursue premium quality bags based on thorough analysis and application of these data.
