How to Choose Large Pet Food Packaging Suppliers

Since 2025, our factory has gradually received more inquiries and orders for large-size laminated pet food packaging bags. Most customized capacities range from 7 kg to 15 kg, or approximately 15 lb to 45 lb.

Through communication with these customers, we found that many pet food brands choose plastic flexible packaging instead of traditional woven bags mainly for brand positioning and better product protection. Compared with woven bags, large-capacity plastic pet food packaging can be designed with reusable zippers, provides better moisture and water resistance, and offers more attractive and flexible printing effects. These advantages make it more suitable for premium pet food brands and higher-end market positioning.

Many manufacturers, especially flour producers, often wonder why we reject larger capacity bags like 25kg and 30kg when purchasing large-capacity packaging bags. In fact, compared to capacity, we should consider the following:

• Can the bag stand stably?
• Is the bottom prone to bursting?
• Can the side seal withstand transport compression?
• Do the handles need reinforcement? 
• Is the zipper suitable for repeated opening and closing?
• Can the seal withstand dust and grease contamination? 
• Is it suitable for automated filling lines? 
  
  

Henan Baolai Packaging works as a reliable packaging partner for large pet food OEM manufacturers, providing professional custom solutions for different product needs, filling processes, and brand positioning. Customization is one of our strongest advantages. We do not provide stock packaging bags, because every pet food project has different requirements in size, material structure, barrier performance, zipper design, printing, and loading strength.

Last year, we supplied large-size dry pet food packaging bags worth nearly USD 1 million to a major pet food OEM factory in Spain. The customer was highly satisfied with the quality and service. More importantly, after receiving our products, they introduced us to other pet food factory customers, which gave us strong confidence in our ability to serve large pet food packaging projects.

• After a large pet food bag is filled, the weight can amplify any weakness in the side seals or bottom seals.
• Dry pet food kibbles may puncture the inner layer of the bag.
• Oil and grease from the product may affect heat-seal strength.
• Dust or fine powder may contaminate the sealing area during filling.
• Long-distance transportation may cause dropping, compression, corner damage, or edge breakage.
• Automatic filling lines may have specific requirements for bag mouth size, opening performance, and heat-sealing window.

Henan Baolai Packaging provides custom large pet food packaging solutions for pet food brands, OEM factories, and bulk food manufacturers.

Unlike standard stock bag suppliers, we design packaging based on your product weight, bag size, barrier requirements, filling process, transportation conditions, and brand positioning. For large dry pet food bags, we can recommend high-barrier laminated structures such as PET / Reinforced Metallized Film / Heavy-Duty PE, or clear structures such as Transparent PET / Heavy-Duty PE, depending on your product and shelf-life needs.

For large-capacity pet food packaging, strength and reliability are critical. We pay attention to side seal strength, bottom strength, puncture resistance, zipper performance, heat-sealing stability, and filling-line compatibility.

Before bulk production, we recommend sample testing to help customers verify the bag structure, loading performance, sealing quality, and overall packaging effect.

If you need a reliable Custom large pet food packaging supplier for dry pet food, freeze-dried food, pet treats, cat litter, or bulk pet food products, Henan Baolai Packaging can support your project from material selection to finished packaging delivery.
