Wholesale carry plastic bags

Buyers should primarily choose between HDPE (High-Density Polyethylene) for strength and a 'crinkly' feel, or LDPE (Low-Density Polyethylene) for a glossy, tear-resistant, and premium feel. For heavy-duty applications, ensure the thickness (gauge) is specified in microns; typically, 15-20 microns is standard for grocery bags, while 50+ microns is required for reusable 'bags for life' to meet certain environmental regulations.

It is critical to verify if the bags need to be biodegradable or compostable. Look for certifications such as EN 13432 or ASTM D6400. If purchasing traditional plastic, ensure they meet the minimum recycled content requirements (e.g., 30% recycled plastic) now mandated in many regions like the UK and EU to avoid plastic taxes.

Focus on the load-bearing capacity and handle reinforcement. For retail, vest-style (t-shirt) handles are cost-effective, while die-cut or soft-loop handles offer a more upscale brand image. Ensure the bottom seal is a 'star seal' or 'flat seal' to prevent leakage and improve weight distribution.

Provide the supplier with vector files (AI or PDF). For large wholesale orders, flexographic printing is the most economical method. Confirm the ink type, prioritizing water-based or soy-based inks which are more eco-friendly and less likely to have a strong chemical odor upon opening the bulk packaging.

Always request a pre-production sample (PPS) before the full run. For wholesale plastic, the most common issue is thickness inconsistency. Specify a tolerance level (e.g., +/- 5%) in your contract and consider hiring a third-party inspector to perform a random G-I level inspection focusing on tensile strength and print alignment.

Leverage the volume-based pricing model. In the plastic industry, prices are heavily tied to raw material resin costs. Negotiate a long-term supply agreement that allows for price adjustments based on global resin indices. On platforms like Made-in-China.com, look for 'Diamond Members' or 'Audited Suppliers' to ensure you are dealing with a factory rather than a small trading company to get direct-from-factory pricing.

Plastic bags are dense and heavy; therefore, sea freight (FCL or LCL) is the only economically viable option for wholesale. Ensure the supplier uses heavy-duty corrugated export cartons and palletizes the load with shrink-wrap to prevent moisture ingress and box collapse during long-term transit in humid shipping containers.

Utilize Secured Trading Services provided by Made-in-China.com to protect your payment until shipping documents are verified. Additionally, check the HS Code (typically 392321) against your country's latest anti-dumping duties list, as some regions impose high tariffs on specific plastic products originating from overseas to protect local industries.
