There are various types of flexible stand-up pouches on the European and American markets, including single-layer PE pouches, PET/PE dual-layer pouches, and paper-plastic composite pouches. However, PET/AL/PE three-layer high-barrier composite pouches have obvious comprehensive competitive advantages in terms of performance, durability, and economic benefits, becoming the first choice for long-term cooperative brands.
In terms of barrier performance, ordinary single-layer and dual-layer pouches have poor air and moisture isolation capabilities, with high oxygen and water vapor transmittance. They are only suitable for low-value products with short shelf life and low environmental requirements. In contrast, the PET/AL/PE structure relies on the aluminum middle layer to achieve ultra-low permeability, with barrier performance dozens of times higher than ordinary pouches, fully meeting the long-term storage needs of high-value products.
In terms of structural durability, the three-layer composite structure has stronger tensile resistance, puncture resistance, and drop resistance. In the process of cross-border logistics, express transportation, and supermarket shelf placement, ordinary pouches are prone to cracking, air leakage, and bag damage, while PET/AL/PE pouches can maintain intact sealing and structural stability, greatly reducing product damage rates and logistics costs for brands.
In terms of comprehensive cost performance, although the unit cost of high-barrier pouches is slightly higher than that of ordinary products, they can effectively reduce product deterioration losses, return costs, and packaging replacement costs. For European and American brands that focus on product reputation and long-term operation, the overall economic benefit is far better than low-cost ordinary packaging.
In addition, PET/AL/PE pouches support richer personalized customization and higher-grade printing effects, which can effectively improve product added value and market competitiveness, helping brands gain more market share in the high-end European and American markets.
