Customized seal plastic bags provide numerous benefits to businesses and individuals. Compared to standard packaging, they feature more targeted designs and stronger seals, making them easier to store and transport, while also offering specialized solutions for various scenarios.

Among resealable plastic bags, eight-side seal bags are particularly popular. Understanding their advantages and diverse applications is essential for anyone aiming to utilize these bags effectively. When choosing or designing custom eight-side seal bags, comparing them to traditional packaging methods can help determine if they are suitable for a particular application and should be included in a packaging strategy.

By exploring these aspects, businesses and individuals can gain a better understanding of custom eight-side seal bags and make informed decisions. MTPAK offers a broad range of flexible packaging solutions for the food and beverage industry, including eight-side seal bags, spout pouches, side gusset bags, flat bottom pouches, and other flexible packaging options.

Why are custom sealed plastic bags important?

Whether it's coffee beans, nuts, or pet food, preserving freshness and flavor is a brand's fundamental promise. While common three-side-seal and stand-up pouches on the market can meet some needs, they have limitations in terms of barrier properties, capacity, and visual appeal.

The value of custom sealed plastic bags lies in their ability to be optimized based on product characteristics: they not only extend shelf life and ensure food safety, but also enhance brand identity through design. While standard-style bags are economical and practical, they cannot convey differentiated brand symbols. Customization allows businesses or brands to strike a balance between cost and benefit, creating greater added value.

If you simply need to store a few household items, standard-style bags are sufficient. However, if your goal is to establish brand recognition and build trust, custom sealed plastic bags are undoubtedly the most effective tool.

What is an 8 side seal plastic bag?

Eight side seal bags are a type of composite packaging bag. As the name suggests, they feature eight sealed edges: four at the bottom and two on each side, ensuring the bag stands securely on shelves.

Compared to common three side seal or stand-up bags, eight side seal bags offer five display surfaces: the front, back, two sides, and the bottom, allowing for better display of product information and branding.

This bag type has gained popularity in recent years and is also known as a flat-bottom bag or accordion zipper bag. Currently, many well-known brands use this bag type. Eight side seal bags are popular among consumers for their three-dimensional appearance and premium appearance.

What are the advantages of 8 side sealing bags as packaging?

1. Practicality

The flat bottom structure allows the bag to remain upright on the shelf, enhancing display effectiveness. This bag type has been widely used in a variety of categories, including dried fruits, nuts, pet food, and snacks, and its aesthetic and practicality are highly sought after by brands and consumers.

2. Flexibility

Eight side seal bags utilize a flexible packaging composite process, offering a wide variety of material options. This allows for flexible design by adjusting thickness, barrier properties, and printing quality, offering far greater versatility than a single box design. Furthermore, they feature five printing panels, providing ample space for product information display.

3. Convenience

Many eight side seal bags feature a resealable zipper, providing consumers with a convenient opening and closing experience unmatched by traditional boxes. Their unique design effectively prevents counterfeiting, makes them easily recognizable to consumers, and contributes to brand building. Furthermore, the option of multi-color printing enhances the product's visual appeal and significantly enhances promotional effectiveness.

Which products are suitable for 8 side sealing bags?

With its unique structure and performance advantages, the eight side seal plastic bag is suitable for a variety of product packaging, especially for products that require high sealing, strong display effects, and extended shelf life.

1. Food

(1) Pet food

Pet food, such as dog food, cat food, and bird food, has extremely high requirements for moisture resistance, oxidation resistance, and pollution resistance. The high barrier structure of the eight side seal plastic bag can effectively lock in nutrients and fragrance, preventing moisture or contamination during transportation and storage. The large capacity design can also meet long-term storage needs, and is highly favored by pet brands.

(2) Grains and cereals

For products that require long-term storage, such as rice, oats, and beans, the sealing and anti-oxidation properties of the eight side seal plastic bag can delay deterioration, while the multi-sided printing design facilitates the display of product information.

(3) Snacks

Nuts, candies, dried fruits and other snacks. The eight side seal plastic bag has a crisp three-dimensional appearance that brings a sense of luxury. The resealable zipper design makes it easy to open and close.

(4) Tea and coffee

Tea and coffee have particularly stringent requirements for moisture and oxidation resistance. Eight side seal plastic bags can be equipped with exhaust valves, aluminum foil layers, or high-barrier films to ensure that the aroma and flavor of tea and coffee remain unchanged during storage and transportation.

(5) Steamed foods

Some eight side seal plastic bags can be made of high-temperature resistant materials to meet the requirements of vacuum packaging or high-temperature steaming processes. They are widely used in categories such as sauces and ready-to-eat meal packs.

2. Non-food items

(1) Cosmetics

Suitable for facial masks, gadgets or sample packaging, the eight side seal plastic bag can enhance the product quality through exquisite printing and three-dimensional appearance. The portability and resealability can also make it easier to accept and repurchase.

(2) Pet products

Such as cat litter, toys, etc., the high load-bearing capacity and anti-pollution properties of the eight side seal plastic bag ensure cleanliness and durability during storage and transportation.

(3) Industrial parts

Small industrial parts such as screws and assembly parts require good sealing and moisture-proof properties. The wear resistance and customizability of eight side seal plastic bags can ensure that parts are not lost or exposed to moisture during transportation, thereby reducing losses.

Conclusion

As consumer demands for food safety, environmental compliance, and brand experience continue to rise, eight side seal plastic bags are gradually replacing traditional pouches and becoming an ideal choice for the food industry. They combine barrier performance, shelf appeal, and sustainable value, helping brands stand out in a highly competitive market.
