2 Foil Materials

This foil material is a reinforced structure with excellent properties for cat litter bag packages. The foil structure is PET12/PA15/LDPE, with a graphic as below.

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

PET12, is one of the most commonly used printing substrates in flexible packaging pouches. With great optical clarity, high gloss, good chemical resistance, stable mechanical strength, excellent dimensional stability, and great printability, it can present the customer artwork print in great quality, and also provide great mechanical strength to the final package.

PA15,which is short for biaxially orientated polyamide film, with the most used thickness 15 microns (equals to 0.6 gauge). Usually people call it nylon film. It is of excellent mechanical strength, anti-puncture resistance and high barrier performance against oxygen. When it is applied into the foil laminate, usually the final package is achieved with reinforced mechanical strength.

LDPE, means low-density polyethylene film, which is the most used inner sealing layer for coffee bags. LDPE is also lightweight, easy to fabricate, and has good chemical and impact resistance. LDPE is recyclable and reusable, making it a popular alternative to traditional plastic. LDPE is nontoxic, non-contaminating, and has a high degree of break resistance. Most importantly, LDPE membrane can be modified against the requirement of specific products, and finalize the package with great seal strength and protection. The thickness of LDPE membrane will be decided against particular

b. Pantone Color Code

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

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.

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 Gas Release Property Test

The gas will be released from the inside when the air pressure for the inside is 2~7 mbar than the outside environment. Usually, we will immerse the valve welded bag under the water, and check if the degassing valve works well.

4.6 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.

4.7 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.

4.8 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.
