It comes with a suction nozzle design, making it easy for pets to consume
The packaging of pet dry food imposes stringent requirements on material puncture resistance, high barrier properties, and sealing freshness preservation. Based on available information, this article summarizes the mainstream types of packaging bags currently available in the market, key material characteristics, and the latest industry trends to assist in your selection and decision-making process.
Ø Comparison of main packaging types
You can select basic bag types based on product shape, capacity, and brand positioning by referring to the table below:
Bag-shaped | main features | Application scenarios and capacity reference |
Three-sided/Four-sided sealed bag | Conventional bag-type, with simple structure and good sealing performance. | Suitable for small-sized meal packages, minced meat, etc. |
Self-contained bags (including square-bottomed bags and corner-folded bags) | It can be placed upright for display, with shelves providing excellent presentation. It is often equipped with a zipper for repeated sealing. | Suitable for various types of wet food and snacks. The capacity range is extensive, commonly from 100g to 15kg. |
posterior closed pouch | The bag features a smoother surface, ideal for printing large, intricate designs, giving it a premium look. | High-end products with high requirements on packaging appearance. |
self-contained bag with mouth/cover | Equipped with a rigid discharge nozzle and a sealing cap, facilitating the extrusion of contents and resealing, ensuring excellent leak-proof performance. | It is suitable for meat paste, thick soup and other viscous or fluid wet grain. |
Vacuum packaging bag | After vacuum sealing, it can effectively isolate oxygen and prolong the shelf life. | High-end wet grain or fresh pet food with high preservation requirements. |
Ø Core Materials and Property Requirements
When selecting wet food packaging, special attention should be paid to the following material properties:
· High barrier properties: Must effectively block oxygen and water vapor to prevent oxidation and moisture loss in wet grain. Common materials include aluminum foil (Al), aluminum-coated film (VMPET), and high-barrier EVOH.
· Puncture resistance and oil resistance: Wet grain may contain bones, hard objects, or high oil content, requiring materials with excellent puncture resistance and oil permeability to prevent bag rupture and oil leakage.
· Heat seal strength: The edge seal must be robust and airtight, capable of withstanding both the pressure from contents and transportation jolts.
· Safety: All inner materials must meet food-grade safety standards.
Ø Industry Trends: Sustainable Packaging
Currently, the use of recyclable single-materials (such as single PE or PP) is a key development direction for pet food packaging. These packaging solutions provide necessary barrier properties while being easy to recycle, significantly reducing environmental impact and aligning with future regulations and consumer preferences. If your brand emphasizes an eco-friendly image, you may prioritize exploring such solutions.
Ø Selection and customization suggestions
· Define requirements: First, determine your product form (e.g., paste or block), capacity, sterilization method (e.g., high-temperature cooking), shelf life requirements, and brand positioning.
· Request sample testing: Obtain sample bags of different materials from the supplier and conduct filling, sealing, drop, puncture, and freshness tests in-house. This is the most reliable method to verify packaging performance.
· Focus on customization details: thoughtful features like the packaging handle, hanging hole, easy-tear strip, zipper, and laser-engraved patterns can significantly enhance both user experience and product prestige.
If you can provide the specific type of wet food you plan to package (e.g. meat chunks, meat paste, broth), the single package capacity, and the main target market, I can offer you more targeted information.
