2 Foil Materials

This foil material is a reinforced structure with excellent properties for dog food bag packages. The foil structure is PET12/PA15/VMPET12/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.

BOPA stands for Biaxially Oriented Polyamide, which is also known as biaxially oriented nylon (short as NY) film. It’s a versatile and flexible material that’s made by biaxially stretching polyamide resins using a flat cast die process, three-layer co-extrusion method, and two-step tenter frame orientation.

VMPET film is short for vacuum metallized polyester film, that is achieved under vacuum conditions to deposit a thin layer of aluminum atoms onto the surface of PET (polyester) film substrate, and finally realize a bright metallic film that is widely used in flexible packaging and standup pouch packages.

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

3 Properties and Quality Assurance

3.1 Exquisite print quality

We bring your artwork to life with state-of-the-art rotogravure printing, capable of producing up to 10 vibrant colors. With advanced printing techniques and an automated print defect inspection system, every detail is carefully monitored to ensure flawless results. The outcome is stunning, high-impact packaging that captures your brand’s essence and delights your customers.

In our manufacturing plant, we take serious measures to achieve high color fidelity and consistency for repeated printed orders, and here we are going to give a basic introduction.

a.  Color Analyzer

Our advanced color analyzer is an essential tool designed to ensure the highest standards of color fidelity. More than just validating CMYK and spot colors, it simultaneously measures across four M modes to deliver precise results. With this capability, it can:

• Visualize the spectral reflectance of substrates or inks

• Measure the concentration of specific inks

• Compare the color difference of substrates or inks over white and black backgrounds

This powerful functionality guarantees accurate, consistent, and reliable color management—empowering your print production with unmatched precision.

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

Digital files such as JPG, PDF, PSD, and AI should not be relied upon as definitive guides for print color. These formats display colors through electronic screens, and variations in screen settings across different devices inevitably affect color presentation.

For accurate color matching, only printed artwork on physical substrates can serve as a reliable reference,most commonly produced on professional photo paper. This ensures consistency and precision in reproducing the intended colors during the printing process.

3.3 Excellent Dimension Stability

There is an increasing requirement for the dimension stability of the dog food bags when the roasters and packers are going to improve the production efficiency with high-speed filling lines. We get quite a good understanding on 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 10kg doog food bag, the tolerance should be controlled within +-2%, which can run well on most of the high-speed filling machineries in the market.

3.4 Delicate Bag Making

The bag is achieved with delicate details, which can create a perfect impression for the consumers when they pass by the products, and cause them a purchase. Some customers do like to buy a product out of its gorgeous profile.

3.5 High Barrier Performance

As explained previously, this foil laminate is finalized with a layer of thin aluminum metal sheet, which is of the best barrier performance against oxygen and moisture vapor. Usually, the dog food should be well protected to keep the original flavor and fragrance for a prolonged period, to enable the dog food enjoyed by the end consumers.

3.6 Fantastic Standup Effect

The bottom of this 10kg dog food bag is much like a box when the dog food are filled, and that will make the package well stand up on the goods shelf, good for branding and sale.

3.7 Great Mechanical Strength

This reinforced laminated foil can greatly protect dog food.

We perform various inspections and tests to check the mechanical strength of the finished pouch, like drop tests, hard sudden strikes, anti-pressure tests

• Tensile Strength
• Sealing Strength
• Anti-puncture Strength
• Burst Impact Strength
• Anti-pressure Property

The above tests are performed against each order, on customer requirements, and you may check the exact values of this foil material PET12/PA15/VMPET12/LDPE in the Technical Date Sheet part of this post.

3.8 Smooth Zipper

The innovative slide zipper design allows the pouch to be opened effortlessly from the tear tab, creating a clean, straight-line opening. This feature maintains the original integrity of the package while offering maximum convenience. The zipper blends seamlessly with the overall design,delivering both functionality and a refined, premium appearance.

3.9 Easy Filling of dog food

Our block bottom dog food bags are designed with a large opening, making the filling process quick, efficient, and hassle-free. This innovative feature allows dog food to be packed smoothly and securely, ensuring both speed and convenience in every step.

Watch the video below to see how easily it works.

With the side gusset and bottom gusset, the bottom of this dog food bag is like a box (that’s why it is also called box bottom pouch), which makes the fall of the dog food much more easily into the bag.

You are advised to see the options of opening on block bottom box dog food bags for the current 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, with the core items evaluated in it.  It is highly appreciated by our customers.

You may read here to understand the QC test report for an order of 250g and 1000g coffee bags.

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 dog food 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 dog food 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

The drop test is one of the most reliable methods to evaluate the strength of dog food bags. It simulates real-life scenarios, such as products accidentally falling from store shelves, where the packaging must withstand sudden impact and shock.

At VP Packaging, we conduct drop tests as part of our routine quality control for every order. This process ensures that each bag delivers the durability and protection your products need. Test standards are customized according to customer requirements, guaranteeing packaging performance that aligns perfectly with your brand’s expectations.

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.

 

4.6 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 dog food 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 dog food 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 dog food bag, to check if there is any burst of them.

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

8 More Sustainable Options

As the global concern over plastic pollution continues to rise, forward-thinking manufacturers are embracing more sustainable packaging solutions. Compostable films, recyclable mono-material pouches, and plant-based alternatives are leading the way, offering eco-friendly options that reduce environmental impact while maintaining product quality.

Unlike traditional plastic films, which are derived from fossil resources and notoriously difficult to recycle or degrade, these innovative materials support a circular economy and help brands align with growing consumer demand for sustainability.

In the dog food market, these sustainable packaging trends are rapidly gaining momentum, setting new standards for both responsibility and performance.

8.1 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.
