Square Packaging Pet Food Aluminum Foil Container

A Better Fit for Brands Looking Beyond Round Pet Food Containers

Round packaging has been a familiar choice in the pet food industry for years. But when every product on the shelf starts looking similar, why not change the container shape to offer a fresh look to customer and give brand a new chance?

The Square Packaging Pet Food Aluminum Foil Container offers a rounded-square format for pet food manufacturers looking for an alternative to conventional round cups.

Its wider top, narrower base and deeper body create a practical structure for portioned wet food packaging. The gold-colored exterior also gives the container a distinctive appearance, while the silver aluminum foil interior maintains the recognizable look of aluminum packaging.

E300 gives wet pet food and special products a fresh packaging option.It’s not just about shelf appeal, though—it also hasto run smoothly on the production line. So before you place a big order, make sure thecontainer size, lid fit, filling process,and shipping details all line up. Yunchu includes E300 in its range of customizable aluminum foil packaging, ready for pet food brands, contract manufacturers, importers, and private-label companies.

E300 Product Specifications

More Room, More Flexibility: What the E300 Design Offers

When you’re picking out a pet food container, it’s got to fit the food, make filling easy, and still be practical when it goes out to stores. The E300 covers three structural details that stand out for commercial packaging.

Wide Square Opening

The top opens up to 112 × 112mm—a pretty broad area. If you’re packing paté, minced meat, or mixed wet food, the width makes things easier during filling. You get more room to arrange and check the product as it goes in.

Tapered Base, Defined Shape

At the bottom, you’ve got 86 × 86mm, so there’s a noticeable taper from top to base. Instead of a basic box, you end up with a square that has rounded corners. It looks distinctive, but it’s also a smart shape for stacking and handling. Of course, you’ll need to check how well it stacks in your own setup.

Deeper Cup: 42mm Height

With a 42mm height, the E300 sits deeper than most of those shallow portion cups you see around. If your brand wants bigger servings or something with a different profile, this container opens up new options for your packaging lineup.

And sure, actual filling weight depends on your food’s density and how much headspace you need—not just the external size. But if you’re after versatility, the E300 gives you a good place to start.

Built Around the Way Pet Food Is Packed

The E300 format can be considered for different pet food categories, depending on the formulation and filling requirements.

Wet Cat Food

Potential applications include:

Pâté-style cat food

Minced wet cat food

Complete meal portions

Mixed-texture cat food

Specialty wet food recipes

For cat food brands with multiple recipes, customized lid designs can help distinguish different product variants without changing the basic container format.

Wet Dog Food

The square structure also provides an option for selected wet dog food products.

It can be evaluated for:

Prepared wet dog food

Pâté-style dog food

Minced meat formulations

Individual feeding portions

Specialty dog food products

Filling weight should be established through actual product trials, particularly for recipes with different moisture content and density.

Private-Label Pet Food

For private-label businesses, the combination of a gold exterior and customized lid artwork offers a starting point for developing a recognizable packaging identity.

Different product names, colors, illustrations and logos can be incorporated into the overall design, subject to the selected printing process.

Specialty and Premium Pet Food

For brands selling specialty recipes or differentiated pet food collections, packaging appearance can support the product's overall market positioning.

The E300 square profile gives buyers another option beyond the standard round packaging format.

The Packaging Details: Foil Lid, Plastic Cover and Branding

A container is only as practical as the closure system that goes with it.

For E300, the supplied images show a gold-colored foil cover with an opening tab. The product-series materials also illustrate transparent plastic covers and other lid formats.

The final configuration should be confirmed according to the E300 dimensions and rim design.

Peelable Aluminum Foil Lid

The gold-colored foil lid shown in the product images provides a coordinated appearance with the container exterior.

Its peel-tab design offers an opening point for end users.

For B2B projects, important details include:

Foil thickness and structure

Sealing layer compatibility

Pull-tab design

Rim dimensions

Peel strength

Required storage conditions

A lid that looks the part but doesn't seal properly? That's a hard pass for any serious food packaging program. Sample testing is the way to avoid that problem.

Transparent Plastic Lid

A compatible transparent plastic lid can be considered when product visibility is important.

It may be useful for selected chilled pet food products, display applications and additional covering requirements.

The specific plastic material and its temperature resistance must be confirmed before use. It should not be used for oven or direct-flame heating unless its specification explicitly permits those conditions.

Custom Printed Covers

For private-label brands, the lid can also serve as a packaging identification surface.

Possible artwork elements include:

Company logo

Pet illustrations

Recipe names

Brand colors

Product identification

Customized graphics

Final printing feasibility, available lid formats and order quantities can be discussed during the OEM/ODM stage.

What's Inside the Gold Aluminum Foil Structure?

The supplied E300 material illustration identifies a thickened aluminum foil construction with several functional layers.

The layered construction is designed to combine a lightweight aluminum body with a distinctive exterior finish and resistance to deformation during normal handling.

Lightweight for Commercial Handling

Aluminum foil offers a practical balance between weight and container structure.

For wholesalers and pet food manufacturers, lightweight packaging can be useful when planning packing, warehousing and distribution.

Thermal Conductivity

Aluminum transfers heat efficiently, making it suitable for compatible heating and baking applications.

This is an additional benefit for manufacturers considering the container for suitable food preparation processes.

Form Stability

The specified hardened layer is intended to support resistance to deformation.

The formed sidewalls also give the container its recognizable square profile.

Recyclable Material

Aluminum can be recycled where appropriate collection and processing facilities are available.

The complete package's recyclability will depend on its coatings, lid material, printing and local recycling infrastructure.

More Than Pet Food: An Additional Baking Application

Although E300 is primarily positioned for pet food packaging, its aluminum foil body can also be considered for compatible baking applications.

The supplied product images describe the container as a baking cup that can also serve as the final presentation package.

For suitable recipes, the baked product can remain in its original container, avoiding an additional demolding and repacking step.

This may be useful for:

Small baked cakes

Individual dessert portions

Brownies

Prepared food portions

Specialty bakery products

It's one less step to deal with during production, which is always a welcome bonus when the kitchen gets busy.

The actual baking temperature, recipe compatibility and lid requirements should be confirmed before use.

Heating Precautions

The supplied product graphic identifies direct-flame heating as an available application.

Please observe the following:

Never heat an empty aluminum foil container.

Confirm the applicable temperature and heating conditions before use.

Remove plastic lids before heating.

Do not assume the foil lid is compatible with every heating method.

Validate the product with the intended recipe and equipment.

The supplied information does not establish that E300 is suitable for retort sterilization or shelf-stable commercial wet pet food production. Those applications require separate technical assessment and testing.

Custom Pet Food Packaging: Make E300 Your Own

Standard packaging is a good starting point, but different brands rarely have identical requirements.

Yunchu provides OEM/ODM aluminum foil packaging services for customers who need more control over the container's dimensions, appearance and accompanying packaging materials.

A Wide Range of Existing Specifications

Our supplied product range covers capacities from 15ml to 6200ml, with more than 200 existing sizes and styles.

This gives customers more room to compare packaging formats across different pet food products.

Custom Container Dimensions

Different dimensions can be evaluated according to:

Required capacity

Top opening size

Bottom dimensions

Container height

Wall and base structure

Filling equipment requirements

Custom Shapes

E300 provides a rounded-square format.

For other projects, different shapes and dimensions can be discussed based on the intended application and mold development requirements.

Custom Logo and Branding

YCALU supports brand-oriented packaging development, including:

Customized logo applications

Printed foil lid artwork

Brand stickers

Product labels

Paper card sleeves

Customized outer cartons

Multiple SKUs Under One Brand

For pet food companies selling several recipes, packaging can be coordinated across different products.

For example, different lid graphics can distinguish cat food and dog food lines, or separate individual recipes, while retaining a consistent container appearance.

This is particularly useful for private-label brands and distributors managing multiple customer requirements.

From First Sample to Repeat Orders

For international buyers, successful packaging procurement is not just about receiving a quotation.

The product needs to fit the filling process, meet packaging requirements and remain consistent when the next order comes around.

Yunchu can coordinate the main stages of an OEM/ODM project.

1. Discuss the Product Requirements

Share the intended pet food application, required fill weight, target capacity and expected storage conditions.

2. Confirm the Container and Lid

Review E300 dimensions, rim structure and the appropriate lid format.

3. Develop the Packaging Design

Provide your brand artwork, logos, labels, stickers or card sleeve requirements.

4. Review Samples

Check the physical container, lid fit, printing appearance and relevant package performance.

5. Confirm MOQ and Quotation

The minimum order quantity, unit price and production lead time will depend on the selected materials, lid configuration, printing requirements and order volume.

6. Start Bulk Production

Production follows the approved specifications and artwork.

7. Inspect, Pack and Ship

Finished products are inspected, packaged and prepared for export according to the agreed order arrangements.

For repeat orders, retaining approved product drawings and artwork files helps reduce unnecessary rework. No last-minute scramble over which logo version was approved.
