Company Verification & Compliance

Transparent Company Identity. Certified Manufacturing Support. Documented Quality Control.

When choosing a packaging supplier, global brands need more than attractive product photos and competitive pricing. They need clear company information, documented compliance support, and a reliable quality control process.

They need to know who they are working with, where the packaging is produced, whether the company information is clear, and whether the supplier can support quality, safety, and compliance requirements.

At Shanghai Cailyn Industrial Co., Ltd, legally registered in China as 上海才霖实业有限公司, we believe trust starts with transparency.

We provide custom packaging solutions for food, coffee, tea, supplements, pet food, beauty, and lifestyle brands worldwide. Our goal is to help customers develop packaging that is functional, reliable, visually appealing, and suitable for global market requirements.

Certifications & Compliance Support

Compliance documentation is an important part of supplier qualification, especially for food, coffee, tea, supplement, pet food, and retail packaging projects.

Cailyn supports customers with certification and testing documentation related to quality management, food contact safety, responsible sourcing, and packaging performance.

Our certification and testing support includes:

BRCGS Packaging Materials

Our manufacturing system is supported by BRCGS Packaging Materials certification, demonstrating our commitment to product safety, process control, quality management, and traceability in packaging production.

FSC® Chain of Custody

We offer FSC® certified paper options for customers who require responsible sourcing and sustainable paper-based packaging solutions.

This is especially valuable for paper boxes, paper bags, labels, and paper-based packaging projects.

Food Contact Testing Support

For packaging that comes into contact with food, we can support customers with food contact safety testing documentation, including FDA-related testing, LFGB / EU food contact testing, heavy metal content testing, and overall migration testing.

These documents help customers evaluate packaging suitability for target markets.

Child-Resistant Packaging Testing Support

For selected child-resistant zipper pouch structures, testing support according to ASTM D3475-20 is available.

This type of packaging is suitable for brands that require enhanced consumer safety features and additional packaging performance verification.

Quality Control Process

Certificates are important, but consistent quality depends on everyday process control.

At Cailyn, quality control starts from material selection and continues through production, inspection, and shipment documentation.

Our quality control process includes:

1. Material Inspection

We review approved suppliers and inspect incoming materials before production to help ensure material consistency and project suitability.

2. Printing Control

During printing, we monitor color, artwork details, registration, and print consistency to help match approved samples and customer requirements.

3. Lamination & Curing

For laminated packaging structures, we control lamination and curing processes to support material strength, barrier performance, and structural stability.

4. Bag / Box Making

During converting and finishing, we check key details such as dimensions, sealing, zipper position, valve placement, window shape, folding structure, and appearance.

5. Final Inspection

Before shipment, finished products are inspected according to agreed specifications, including size, printing, sealing, structure, packing method, and overall appearance.

6. Shipment Documentation

We support order review, packing confirmation, shipping coordination, and necessary documentation to help customers manage international supply more efficiently.

Why This Matters for Global Brands

For international buyers, packaging quality affects more than product appearance.

It can influence shelf performance, product protection, regulatory review, customer experience, and long-term brand trust.

Working with a packaging partner that provides clear company information, documented compliance support, and structured quality control helps reduce sourcing risks and improve project confidence.

At Cailyn, we aim to make custom packaging easier, safer, and more reliable for global brands.
