Description

Introduce

This 150ml standing spout pouch is popular in the consumer market for kids’ yogurt. It provides a robust and visually appealing container for the merchandise. The pouch’s excellent standing ability makes it ideal for branding and delivering the product effectively.

As a reliable manufacturer of these standing spout pouches with spouts & closure systems for various liquid products, we are going to share the details of this standup spout pouch.

Laminated Foil

Usually, a monolayer film material is not feasible to achieve the multiple functions required by this 150ml yogurt doy-pack. To achieve a robust package, this yogurt pouch will have to be made of a 2-layer structure, with the details of this foil laminate shown in the graphic below.

Generally, we name the foil structure PET12/LDPE, so it can be well understood in business activities. This laminated foil also extends its wide application to many other liquid products, such as jelly, milk, milkshakes, etc.

In this foil laminate, PET film works as the outside print substrate film layer, and LDPE film works as the inner sealing film.

Please note, that all the film materials, inks, and adhesives applied in our flexible packaging are certificated human food safety. Then, let’s get into a better understanding of each of the substrate films.

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.

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 the LDPE membrane will be decided against the particular application.

The overall thickness of this foil laminate is 120 microns. It should be good enough to meet the requirements of a 150ml yoghourt.

To learn more about PET12/LDPE Foil Laminate and how it may assist you in selecting the best packaging, you can read this article on our company website.

Ok, let’s get into a deeper understanding of the performance of this yogurt beverage standup pouch.

3 Properties and Quality Assurance

3.1 Exquisite print quality

The artwork is created using gravure on our rotogravure machine, which has a maximum color capability of 10. We are now achieving exceptional print results when compared to clients’ artwork thanks to modern print techniques and a print flaw detection system.

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 very helpful in locating a specific color for the printing service supplier and the customers, especially if there is a large area printed in a 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

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. 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 the physical substrate, with the most common photo paper applied.

3.2 Excellent standup effect

With the reinforced double-layer material, the pouch is able to present an exquisite standing effect when 150ml of yogurt liquid is filled. In the below video, you will have an actual understanding.

3.3 Great Mechanical Strength

The self-standing spout pouch must keep the 150 ml of yogurt in good condition during transit and distribution. You can easily image what a catastrophe it would be if one of the standup pouch containers broke and contaminated the environment.

We put 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 one 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 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.

You may watch the video below to understand the test process on this 150 ml yogurt doy-pack.

Through the video, you can see, this doypack will not break after 3 drops from 1.6 meters high. They are awesome.

3.4 Eye-catching Effect

This pack of 150 ml yogurt becomes one of the top picks when it just stands on the shelves. People may not help to lay an eye on it when they just browse the products. It surely helps on the product sale.

3.5 Good Dimension Stability

There is an increasing requirement for the dimension stability of the spout pouch when the manufacturers and packers are going to improve the production efficiency with high-speed filling lines. We have quite a good understanding of this and are doing our job to narrow the tolerance of the dimensions for each order produced in our long-term supply. Usually for the 500ml spout bag, the tolerance should be controlled within +-1%, which will run well on most of the high-speed filling machineries in the market.

3.6 Easily To Drink

When the yogurt is ready to be consumed, it may be easily poured out of the flexible pouch. Unlike plastic bottles and canisters, the multilayer pouch is flexible and can be used in a variety of orientations, making it ideal for dining.

3.7 Counterfeit Available

To achieve the counterfeiting purpose, a plastic circle is placed beneath the closure’s top. When the cap is inserted into the plastic spout, the plastic circle is sealed under the hooks. People will have to destroy the closure in order to get to the interior products, which is crucial for product safety.

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

3.8 Delicate Bag Making

The self-standing bag is made with delicate elements that can make a superb impact on consumers as they pass by the products and prompt them to make a purchase. Some buyers prefer to acquire a product because of its attractive profile.

3.9 Plastic reduction

This 150 yogurt spout pouch reduces the plastic materials used against plastic bottles and canisters. Along with that reduction, the transportation cost of this pouch to the customer site can be reduced. So, the self-standing pouch is considered a very economical package option for yogurt manufacturers

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.

 

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 an 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 an 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.

Video Airtight property test #

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 a 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 on inflated spout 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 faster 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 Easy Screw-Off of the Closure

The closure will need to be screwed off the plastic spout without much strength, otherwise, it may be an obstacle for the old and weak people to use the products. This is put on our checklist in our QC work, and through the below video, you will be able to understand the screw-off test of the closures.

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 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.

4.9 Third-party Inspection

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

5 Human Food Safety

All the film materials, inks, adhesives, and solvents used to convert into kinds of food bags and packaging materials will comply with the regulations for human food safety. The below graphic shows the mass spectra in migration tests on these multilayer flexible pouches that are in direct contact with foods.

7 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 more eco-friendly and 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.

7.1 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. Metalized BOPLA Membrane

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

Some of the common compostable foil structures are listed below.

• Kraft Paper/PLA+PBAT Membrane
