GuoZhao Shrink-Film Labels Gain Global Recognition

Strict quality control and innovative technology secure increased orders and deeper cooperation from global customer.

Recently, a world-renowned fast-moving consumer goods company conducted a comprehensive factory audit at GuoZhao Packaging (guozhaopack.com). The client thoroughly inspected our shrink sleeve label production lines, quality control systems, and R&D innovation capabilities.

The inspection yielded outstanding results. The customer expressed high approval of our heat-shrinkable label production capabilities and immediately committed to significantly increasing order volumes and establishing a long-term, in-depth cooperative relationship.

01 Superior Products: The Foundation of Trust

During the inspection, the client focused extensively on our end-to-end production process for shrink film labels. GuoZhao Packaging's shrink sleeves utilize eco-friendly materials like PVC, PP, PETG, and OPS, with thickness precisely controlled within the 30-70 micron range, primarily offering 40, 45, and 50-micron specifications.

We demonstrated how precise control over the transverse shrinkage rate (50%-52% and 60%-62%) and longitudinal shrinkage rate (6%-8%) ensures the labels conform perfectly to the container's contour during the heating process at approximately 70℃, achieving a seamless fit even for irregularly shaped bottles.

“We are deeply impressed by the professional technical expertise demonstrated by GuoZhao Packaging in heat-shrink label production,” the client representative stated in their feedback. “Their profound understanding of material properties, printing processes, and shrinkage control guarantees high-quality final products.”

02 Professional Production Lines: Demonstrating Technical Prowess

During the tour, the client visited our gravure and flexographic printing production lines. We showcased the complete workflow for shrink sleeve labels, from printing to the finished product, including:

· Corona treatment: Enhancing the surface energy of the film to improve ink adhesion.

·Tension control: Ensuring precise print registration.

·Drying temperature control: Preventing film deformation and ink smudging.

·Eco-friendly ink application: Using specialized solvent-based inks to ensure vibrant colors and high gloss in patterns.

We specifically showcased the production processes for both shrink sleeves and shrink wrap labels. The sleeve labels are ideal for contoured containers, while the wrap labels often use PP film with a shrinkage rate typically below 20%.

03 Sustainable Development: Aligning with Global Trends

The client showed particular interest in our environmental technologies and sustainability initiatives. We presented our latest eco-friendly material, PET shrink film, which is recyclable, non-toxic, and odorless, meeting international environmental standards.

We also introduced innovations in film downgauging, which reduces material usage, leading to cost savings and a lower carbon footprint. Additionally, we showcased shrink sleeve materials incorporating Post-Consumer Recycled (PCR) content, which match the clarity, print quality, and shrinkage performance of standard PET shrink films.

04 Customer Recognition: From Orders to Strategic Partnership

Following the inspection, the client praised our technical capabilities and quality management system highly. They particularly appreciated our professional handling of barcode print quality control, ensuring scannability even after graphic shrinkage.

Based on the excellent performance during the audit, the client decided to increase their order volume by 150% and plans to establish a long-term strategic partnership with us. This positions us as a key partner in their global supply chain for developing new shrink film label applications.

The client representative commented, “The professional capabilities and quality assurance system demonstrated by GuoZhao Packaging in the field of shrink sleeves are remarkable. We believe that partnering with them will enhance the market competitiveness of our product packaging, particularly through vibrant visual effects and perfect packaging conformity.”

With the global shrink label packaging market expected to maintain a 4.70% CAGR from 2025 to 2031, this recognition from an international customer signifies that GuoZhao Packaging’s expertise in the shrink sleeve sector has been validated by the global market, laying a solid foundation for the company’s internationalization strategy.
