3 Properties and Quality Assurance

3.1 Exquisite print quality

The artwork is printed through gravure printing on our rotogravure print press which can print up to a maximumly 10 colors. With advanced print techniques and a print defects inspection system, we are now outputting fantastic print results against customers’ artwork.

In our manufacturing plant, we take serious measures to achieve high color fidelity and consistency for repeated print orders, and here we will give an overall introduction.

a.  Color Analyzer

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

The pantone color guide would be so helpful to locate a specific color for the printing service supplier and the customers, especially if there is a large area printed in single Pantone color. For many Pantone colors, the accuracy may be influenced by the printer, paper substrate, and environmental factors when it is printed onto physical photo paper. Pantone Color Code will be located in the artwork design with the customers before the order is put into production.

c. Physically Printed on Photo Paper

The computer files such as JPG, PDF, PSD, AI etc cannot 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 color 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 more about how our company ensures color fidelity and consistency for all our orders.

3.2 Great Mechanical Strength

The self-standing spout pouch will have to protect the 120 grams of Heinz-tomato-ketchup in a fine situation during transit and distribution. You can easily imagine what a nightmare it is when one of the standup pouch packages breaks and contaminates the surroundings.

We put the mechanical strength on the top list of our QC work, and there are serious measures and tests taken in our plant, to ensure each and every of the pouches delivered to the customer site is accountable.

Put simply, a drop test should be considered one of the most reliable ways to check if the spout pouch is robust enough for protection purposes.  Usually, we fill a certain amount of water into the spout bag, and drop it from a certain height, and see whether it breaks when the filled pouch reaches the ground. Of course, the height should be decided against the requirements of the customer’s needs.

3.3 Eye-catching Effect

This 70 ml tomato ketchup stands out naturally on the shelf with its compact and eye catching presence. Even during casual browsing, it easily draws attention and invites a closer look. Its clear visibility and convenient size make it a strong choice that supports impulse interest and encourages purchase.

3.4 Good Dimension Stability

As manufacturers and packers continue to improve production efficiency through high speed filling lines, dimensional stability has become increasingly important for 70 ml tomato ketchup spout pouches. We have a strong understanding of this requirement and consistently work to tighten dimensional tolerances for each order supplied under our long term cooperation.

For a 70 ml spout pouch, the dimensional tolerance is normally controlled within plus or minus one percent. With this level of precision, the pouch runs smoothly on most high speed filling machines currently available in the market.

4 Quality Control Measures

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 apply a strict recording system to document the manufacturing details, such as environmental conditions, craftsmanship parameters, production facility conditions, etc, which allows us to trace back whenever there is a problem.

4.2 QC Test Report Against Each Order

There will be a QC test report issued against each order produced in our plant, with some main items of the properties tested and listed. This is an effective way to get the customers settled on their packages, and highly appreciated by our customers.

You may read here to understand the QC test report of this 120 grams Heinz-tomato-ketchup order.

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’s artwork to be achieved in a way that deteriorates their business. On our gravure print press, there is in-line inspection system that 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 spout 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 30,000 bags printed against customer artwork design.

4.4 Airtight Property Test

The finished spout pouch should be completely airtight, otherwise the product may deteriorate under the conditions of oxygen and moisture in the environment. The closure will need to be screwed tightly onto the spout during the filling process when it is done at the customer site.

Here, we apply airtight property test on this capped spout pouch under the minus-pressure environment, and this proves to be the most reliable way in our industry to check if the package is completely tight from the air.

You are advised to watch the video below for a further understanding on this test process.

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 5 times.

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

After 5 drops for each bag, none of them breaks,  all are fine and dandy.

4.7 Hard Sudden Strikes

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.

The leakage or breakage of the 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.

4.9 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 to gain 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. You may check more of these tests in the Technical Data Sheet part of this post.

4.10 Third-party Inspection

Third-party inspection is available for all our orders on agreed standards or regulations.

8 More Sustainable Options

With the increasing burden on plastic pollution, more and more manufacturers are now seeking more sustainable packages, like compostable film materials, recyclable mono materials packages, and plant-based materials packages. They all prove to be eco-friendlier and more sustainable than the traditional plastic films which are usually derived from fossil chemicals, and very difficult to recycle and break down in the environment.

Here, we are going to share some of the trending sustainable packages for the coffee market.

9.1 Compostable film material packages

Thanks to the fast development of plant-based film materials, we can present the multi-layer standup pouch and roll foils in full compostable and biodegradable options.

 

The compostable substrate films we adapt to convert the multi-layer flexible pouches are listed below.

1. BOPLA Film
2. PLA+PBAT Film
3. Kraft Paper
4. Metallized Paper
5. Cellulose Film
6. Metallized Cellulose Paper
7. PBS Film
8. PVDC Coated Cellulose Film
9. Metallized BOPLA Membrane

We are now achieving multilayer compostable foil materials based on extrusion coating lamination, solvent-free lamination and dry lamination, and then convert into various types of flexible pouches against customers’ requirements.

Some of the common compostable foil structures are listed below.

• Kraft Paper/PLA+PBAT Membrane

Here, we are going to introduce the main performance of these compostable materials pouches.

a. Compostable

All the film materials we adapt are certificated compostable, under home or industrial conditions, complying with the standards EN 13432 or ASTM 6400.

 

 

 

 

 

 

 

 

 

 

The films will present different biodegradation behaviors under different conditions, such as industrial composting facilities, home and garden conditions, and nature soil conditions.

In most cases, industrial composting will be able to achieve a faster biodegradation of the compostable film materials than other composting progress, as it is able to provide better conditions.

Some manufacturers would like to have a better biodegradation behavior of their own compostable packages under nature soil conditions, as in most cases, the abandoned package may not be recycled into human composting facilities.

You may read here to have a better understanding of the break-down progress of our compostable foil laminated materials under the nature condition in Qingdao, Shandong, North China conditions.

b. High-barrier performance pouches

Through vacuum metallization, PVDC coating, and AlOx/SiOx depositing, the compostable films can be achieved with better barrier performance, such as water vapor transmission rate (short as WVTR) and Oxygen Transmission Rate (short as OTR). Later on, we will combine several layers of the barrier film and convert into laminate foil, with an improved barrier property for finished packages.odles, or soup products

In below table, we are going to share some barrier data of the most common foil laminates tested on our Mocon permeation tester.
