Low Density Polyethylene Bags for Food & Retail Packaging

Low density polyethylene bags (LDPE bags) from Xiamen Richer Plastic Co., Ltd. are valued for their flexibility, stretchability, and moisture resistance, making them ideal for a wide range of applications in retail, food service, manufacturing, and household use. LDPE, a soft, lightweight plastic material, gives these bags unique properties: they can stretch without tearing (suitable for packaging irregularly shaped items), conform to contents (reducing wasted space), and provide a tight seal against moisture (protecting items from humidity or spills). Backed by the company’s 20+ years of plastic manufacturing expertise, LDPE bags are produced to meet strict quality standards, ensuring consistency in thickness, strength, and performance across every batch. In retail, LDPE bags are commonly used as produce bags (for fruits, vegetables, or bulk items like grains), thanks to their flexibility and food safety compliance (FDA-approved for direct food contact). They are also used as small promotional bags for giveaways (e.g., samples at trade shows) or as gift bags for small items (jewelry, cosmetics). In food service, they serve as sandwich bags, pastry bags, or takeout bags for lightweight items—with options like resealable zip locks to keep food fresh. In manufacturing, LDPE bags are used as protective covers for small parts (like screws, nuts, or electronic components), preventing dust and scratches during storage or shipping. A cosmetics brand, for example, partnered with Xiamen Richer Plastic to produce small LDPE bags with a resealable zip lock for packaging sample-sized skincare products. The bags’ transparency allowed customers to see the product, while their flexibility made them easy to include in subscription boxes—enhancing the brand’s unboxing experience. The bags’ compliance with FDA standards also ensured they were safe for contact with skincare ingredients. Xiamen Richer Plastic’s manufacturing process for LDPE bags involves specialized film-blowing technology to produce thin, flexible LDPE film—critical for achieving the material’s signature stretch and moisture resistance. The company’s 13,000-square-meter facility is equipped with 24 film-blowing machines optimized for LDPE, which can produce film of varying thicknesses (from 0.01mm to 0.05mm) and widths (from 10cm to 100cm). 44 cutting machines then shape the film into bags of different sizes, from small 5x8cm produce bags to large 50x70cm storage bags. Eight printing machines are available for adding logos, barcodes, or usage instructions—using flexographic printing that adheres well to LDPE’s smooth surface, ensuring graphics remain visible even after stretching. Quality control for LDPE bags includes testing for stretchability (verifying bags can stretch to 200% of their original size without tearing), moisture resistance (checking for leaks when filled with liquid), and seal integrity (for zip-lock variants). The company also offers eco-friendly LDPE options, such as biodegradable LDPE (compliant with EN13432 and ASTM D6400) or recycled LDPE, for clients seeking sustainable alternatives. With an annual production capacity of 2,500 tons, Xiamen Richer Plastic can handle orders of all scales—from 1,000 bags for a small bakery to 1 million bags for a national supermarket chain. The order process is customer-centric: a dedicated account manager works with clients to define size, thickness, and customization needs, provides a quote within 24 hours, and supplies samples for approval.
