Safe Storage, Custom Worry-Free

PP multi-layer containers are safe, stackable, and built for function. They are a smart storage to industries handling powders, dry foods, cosmetics, and more. This article will explain their main uses, design structure, and how they outperform other packaging in preserving freshness, cutting waste, and supporting brand customization.

Applications of Our PP Multi-Layer Containers

Our PP multi-layer bottles or tanks are used in multiple industries. They are suitable for storing solid and powdered products. That’s because of their sealing strength and moisture resistance. Here’s a look at their main applications:

Milk Powder and Infant Formula

Maintaining product freshness is important for food items like milk powder. The moisture-proof and odor-free design of our bottles helps keep the contents dry and uncontaminated. The inner layer is also smooth. That’s why you can clean them easily between uses.

Health Supplements and Nutraceuticals

Health care products such as protein powders, capsules, and vitamins can be protected inside our PP containers. The barrier layer reduces exposure to humidity and oxygen. It can support product stability.

Daily Chemical Products

Our containers can store everyday chemical products safely. So, you can use them for storing laundry powders, cleaning agents, and other products. They have resistance to strong ingredients, so you can use them repeatedly.

Dry Food and Condiments

Our PP multi-layer containers offer a strong seal and odorless storage. So, you can use them for storing grains, spices, coffee, and sugar.

Cosmetics and Personal Care

You can also use our PP multi-layer containers for beauty powders, facial masks, and scrubs. The containers have an airtight feature and neat inner walls so they can maintain product consistency and hygiene.

Main Features of PP Multi-Layer Bottles

Safe and Non-Toxic Material

Our PP multilayer containers are made from food-grade polypropylene (PP). So, they are odorless, BPA-free, and comply with food contact safety standards. You can safely use them for storing food, personal care, and medical-related products.

Durable Multi-Layer Structure

The PP multi-layer containers have a triple-layer design. PP for the outer and inner walls, and EVOH (Ethylene Vinyl Alcohol Copolymer) as the middle layer. This structure improves storage performance without adding unnecessary weight.

Barrier Protection

EVOH is known for its excellent resistance to carbon dioxide, oxygen, and other gases. It protects contents from moisture, air, and odors. They can help products stay fresh for longer periods.

Customizable Design

The lids can be customized to fit your branding needs. They can include built-in spoons, and both the color and shape can be changed depending on your preference. You can also print your logo directly on the lid or bottle surface.

Stackable & Space-Saving

These PP multi-layer containers have a compact shape and a strong body. This allows you to stack and store them easily. Whether on a warehouse shelf or in a home kitchen, they help save space.

Lightweight & Drop-Resistant

The materials used make the PP multi-layer containers strong yet light. They’re easy to carry and less likely to break if you drop them accidentally. This makes them ideal for e-commerce shipping and bulk logistics.

Smooth and Easy-to-Clean Inner Wall

We design the inside of the PP containers with hygiene in mind. The inside is non-stick, so powder doesn’t cling. You can rinse or wipe it clean with minimal effort.

What Are These Bottles Made Of?

Our PP multi-layer bottles combine 3 main materials that work together for long-lasting performance and freshness protection:

Polypropylene (PP) – Inner and Outer Layers

• Known for its toughness and chemical resistance.
• Safe for direct contact with food and cosmetics.
• Lightweight and heat-resistant.
• Easy to mold into various shapes.
• Odorless and non-toxic.

EVOH – Middle Layer (Barrier Layer)

• Acts as the protective core.
• Blocks gases such as oxygen and carbon dioxide from entering or escaping.
• Keeps aroma, flavor, and color intact for a longer time.
• Highly transparent and flexible.
• Often used in food and pharmaceutical packaging due to its gas resistance.

While EVOH can lose barrier strength when exposed to high humidity, using it between two PP layers solves this issue. The outer PP layer blocks moisture. Meanwhile, the inner layer holds and protects the product. This combination ensures a high barrier function even in less controlled environments.

Why Use Multi-Layer Bottles?

Many single-layer containers can’t match the performance of a multi-layer structure. Here’s why our PP multi-layer containers offer more value:

• Longer Shelf Life: Products last longer without flavor loss or clumping.
• Improved Brand Presentation: Our custom design options enhance shelf appeal.
• Versatile Use: From food and pharmaceuticals to homecare goods, one container can serve many purposes.
• Reduced Waste: Our containers are refillable and easy to clean. You can reuse them.

Customization for Branding and Functionality

Srlon supports flexible custom packaging solutions. Whether you’re building a private label or launching a new product, we help you match your container with your visual identity and product requirements.

Available Custom Options:

• Lid Shape and Color
• Spoon Holder at the Top of the Lid
• Surface Logo Printing
• Bottle Color and Opacity
• Size Adjustments (e.g., 1200ml and others)

This gives you full control over how your product looks and feels in the customer’s hands.

With experience serving clients from the food, cosmetics, and pharmaceutical sectors, we understand the unique packaging needs of different industries. Our containers meet strict quality and safety expectations. They can be produced at scale with consistent quality.

Our team works closely with you to guide material choices, barrier needs, and shape design. From prototype to mass production, we ensure that every bottle meets your product goals.

Sustainable and Practical

At Srlon, we also care about responsible packaging. PP is widely recyclable in many regions. And because our bottles are refillable and reusable, they reduce the demand for single-use packaging.

The stackable shape means lower shipping volumes and better space management during transport. This helps reduce logistics-related energy and cost.

How PP Multi-Layer Bottles Are Manufactured

Our PP multi-layer containers are made using co-extrusion blow molding. This process combines 3 layers—PP as the inner and outer layers, and EVOH as the middle barrier layer. The materials are melted and layered together. Then, they are formed into a parison. The parison is inflated in a mold to shape the bottle. Once cooled and trimmed, we will inspect each bottle for quality. This method ensures strong sealing, lightweight strength, and high oxygen resistance. This makes the containers ideal for keeping contents fresh and safe.

How PP Multi-Layer Containers Compare to Other Packaging Materials

When selecting packaging for food, supplements, or household products, it’s helpful to understand how PP multi-layer bottles perform compared to other popular materials. Here’s a closer look.

Compared to PET (Polyethylene Terephthalate)

PET bottles are a common choice for drinks and lightweight food packaging. They give decent moisture protection and are visually appealing due to their clarity. However, when it comes to oxygen barrier performance, PET falls short.

Our PP multi-layer containers offer much better protection against oxygen ingress. They help to preserve the freshness of dry or sensitive contents. PP also withstands moderate heat better than PET. They have greater flexibility for customization in shape, color, and lid design.

Compared to HDPE (High-Density Polyethylene)

HDPE is widely used for containers that require strong chemical resistance, such as cleaning products or personal care liquids. HDPE performs well in that respect. But it has poor gas barrier properties and is fully opaque. This limits its use in packaging that benefits from partial visibility.

In contrast, our PP multi-layer containers offer high gas barrier protection thanks to the EVOH layer. You can use them for preserving food-grade powders or supplements. They’re also more visually versatile and stack more efficiently.

Compared to Glass

Glass is commonly seen as the premium option for preserving product freshness. That’s because it naturally blocks air and moisture. However, it’s heavy, fragile, and more expensive to transport. Glass also poses a safety risk in environments where breakage is a concern.

PP multi-layer containers give a practical alternative by providing high barrier protection in a lightweight and shatter-resistant form. They’re easier to carry and safer for households with children. They are also more cost-effective when considering shipping and handling.

Conclusion

Our PP multi-layer bottles offer reliable storage with added customization. They are designed with practical needs in mind. They serve businesses looking for airtight, lightweight, and easy-to-clean packaging.

From food safety to design flexibility, we focus on making containers that protect your product while helping your brand stand out. Our advanced barrier system using EVOH ensures freshness. Also, our custom options support your packaging strategy.
