If we want to custom flexible packaging, what should we pay attention to?

From shopping malls and supermarkets to specialized retailers, businesses everywhere rely on custom packaging to build brand recognition. Whether it's standard plastic bags, vacuum-sealed pouches, or retail packaging, printing corporate logos and relevant content is essential. Therefore, customizing flexible packaging has become a standard practice. But what exactly should you pay attention to during this process?

1. Strategic Selection of Materials
When customizing flexible packaging, choosing the right material is the foundational step. Currently, the primary production materials for packaging bags are Polyethylene (PE) and Polypropylene (PP).
It is crucial to understand their distinct properties. Generally, Polyethylene (PE) is non-toxic, odorless, and considered more environmentally friendly, making it a preferred choice for direct food contact and general retail use. On the other hand, certain types of Polypropylene (PP) may have different safety profiles depending on their formulation and additives. Because their physical properties and safety standards differ significantly, you must carefully select the appropriate material based on the specific purpose and contents of your packaging.

2. Precision in Size and Compliance
One of the greatest advantages of custom flexible packaging is the ability to determine the exact model and size to fit your products perfectly. Take supermarket carrier bags as an example. While there are generally large, medium, and small standard sizes, these are not rigidly unified across all manufacturers. The dimensions can and should be adjusted according to the specific needs and branding strategies of the supermarket.

Furthermore, compliance is non-negotiable. For instance, convenience bags in supermarkets must adhere to strict regulatory standards. They are required to be printed with nationally standardized logos, such as food safety marks and recycling symbols. Only packaging that features these mandatory safety-related signs and complies with local regulations can be legally put into use.
