PET-Film
PET, or Polyethylene Terephthalate, is a widely used high-performance polymer in flexible and rigid packaging. Known for its clarity, strength, and chemical resistance, PET serves as an excellent structural layer in multi-layer packaging, providing both durability and barrier protection. Its stable molecular structure helps maintain product integrity, making it suitable for a wide range of liquid and powdered products.
Key advantages of PET include:
-
High strength and durability, resistant to punctures, tearing, and deformation, ensuring reliable protection during storage and transport.
-
Moisture and chemical resistance, providing excellent protection against water, oils, and many chemicals to keep the product safe and stable.
-
Transparency and printability, offering a clear surface that supports vibrant graphics and labels, enhancing shelf appeal.
-
Temperature stability, performing well under a range of temperatures, suitable for both ambient and refrigerated conditions.
-
Compatibility, easily laminated with other materials like PA or LDPE to create multi-layer structures that meet diverse packaging requirements.
PA,or Polyamide, is a high-performance material commonly used in flexible packaging for its strength and protective qualities. As a functional barrier layer, PA enhances the durability and integrity of multi-layer packaging, helping to preserve product quality over time. Its tightly packed molecular structure makes it particularly effective at protecting products that are sensitive to oxygen, moisture, or physical stress.
PA stands out for its excellent barrier against oxygen and odors, helping maintain freshness, original flavor, and overall shelf life. It also provides impressive mechanical strength, resisting punctures, tears, and other damage during handling and transport. PA performs reliably even at low temperatures, making it suitable for refrigerated or frozen products. Its compatibility with various materials enables versatile laminated structures, while its chemical resistance to oils and other substances ensures broad applicability across food and non-food packaging.
LDPE,or Low Density Polyethylene, is a versatile and widely used polymer in packaging applications. It is often utilized as an inner or sealing layer in multi-layer structures, providing flexibility, softness, and reliable sealing performance. LDPE ensures that the package maintains its shape and integrity while offering a smooth surface in contact with the product.
Key benefits of LDPE include strong heat sealability, enabling secure seals even at relatively low temperatures. Its flexibility and toughness make packaging resistant to cracking or deformation during handling and transport. LDPE also provides effective moisture resistance, helping to protect products from humidity and environmental exposure. Chemically stable and safe for direct contact with food, LDPE is suitable for a wide range of food and non-food packaging applications. Its ease of processing and compatibility with other materials make it an important component in many flexible packaging designs.
The video below provides a closer look at the print quality and overall finish of this washer fluid pouch.
We implement strict controls in our manufacturing process to maintain high color consistency for repeated print orders. Below is a basic introduction.
a. Color Analyzer
Color Analyzer Checking
This color analyzer is one of the auxiliary tools in our system to achieve the highest standard for color fidelity. The eXact Advanced doesn’t just validate the color of CMYK and spot color inks, it can simultaneously measure four M modes to visualize the spectral reflectance of a substrate or ink, measure the concentration of a specific ink, and measure the difference of a substrate or ink over white and over black.
b. Pantone Color Code
Pantone-color-print-examine-coffee-bag
Pantone color guide would be so helpful to locate a specific color for the pring service supplier and the customers, especially there is a large area printed in single Pantone color. For many Pantone colors, the accurateness may be influenced by the printer, paper substrate and environmental factors when it is printed onto physical photo paper. We will locate the Pantone Color Code with the customers in their artwork design before the order is put into produce.
c. Physical Printed On Photo Paper
Print-proofs-printed-on-photopaper
The computer files such as JPG, PDF, PSD, AI etc can not be taken as the guide to determine the color in print produce, as they present the colors through electronic screening devices. And different electronic screens may be set in different parameters by the various manufacturers, which will inevitably interfere with the colore presentation. Artwork can only be a reliable guide when printed on physical substrate, with the most common photo paper applied.

You may read here to understand the QC test report for an order of 250g and 1000g coffee bags.
4.3 Print Inspection
Pantone-color-examine-purple
In our manufacturing plant, print inspection is treated as a critical control step and is carried out with great care. We never allow customer artwork to be produced in a way that could negatively affect their brand or business. On our gravure printing presses, an in line inspection system is installed to identify and eliminate more than 98 percent of printing defects during the production process.
You may also review how this system operates directly on our control panel, where inspection results are monitored in real time.
There is also a supplementary off-line inspection equipment, to allow us to do the print inspection again whenever it seems necessary.
off-line-gravure-print-inspection-for-roll-foils
We are currently producing coffee bags based on customer provided artwork, and we are committed to supporting our customers during their startup and market testing stages. To make this process more accessible, we offer a minimum order quantity of 10,000 bags printed with customer artwork, allowing brands to test the market with greater flexibility and confidence.
4.4 Airtight Property Test
The finished coffee bag must be completely airtight to ensure the product is effectively protected from oxygen and moisture in the surrounding environment. To guarantee this performance, we conduct an airtightness test on every order using the testing device shown below.
Airtight-property-test-on-sealed-bottom-gusseted-bag
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 coffee bags
hard-strike-on-inflated-coffee-bag
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
anti-pressure-test
Pressure resistance testing is another effective way to evaluate whether the final package can provide reliable protection for the product. This test is especially important for liquid products such as household detergents and windshield washer fluids. For coffee bags, we carry out anti pressure testing as part of our daily QC procedures to ensure each order delivers strong mechanical performance.
Leakage or breakage of a coffee bag would be a serious issue for both distributors and manufacturers, and it is something we never want to see happen in our customers’ business. That is why we place strong emphasis on this testing process.
In some cases, for quick and practical verification, a well sealed and inflated coffee bag may be subjected to a simple load test by having one person stand on it. This straightforward method helps confirm the bag’s resistance to bursting under pressure.
