High Flow Thin-Wall Food Grade Injection Molding PP | Ningmei 1040TE Homopolymer Polypropylene
Product Overview
Ningmei 1040TE is a high-flow homopolymer PP manufactured via Novolen gas-phase polymerization. Its uniform molecular structure is lightly modified with ethylene to deliver balanced toughness. The pellets are ultra-clean, free of black specks, with low ash and gel content. Boasting a steady MFR ranging from 58 to 62 g/10min, it delivers exceptional melt fluidity to fully fill ultra-thin molds and enables short-cycle high-efficiency injection molding. Molded goods feature low haze, high rigidity, reliable heat resistance and zero unpleasant odor. Compliant with GB 4806 food contact standards, this grade fits high-speed injection molding for all kinds of disposable food packaging and transparent thin-wall articles. Consistent batch performance and stable domestic supply make it a cost-efficient raw material for thin-wall food packaging manufacturers.

Core Product Advantages
Ultra-high melt flow for high-speed thin-wall injection molding
With an MFR stabilized near 60 and uniform molecular structure, the resin offers a broad processing window. It fully fills thin parts of 0.3–2 mm wall thickness, drastically cutting molding cycle time and lifting machine output and finished product yield.
High rigidity paired with balanced toughness for stable dimensions
Ethylene modification balances rigidness and low-temperature toughness, with flexural modulus above 1600 MPa. It greatly reduces sink marks and warpage, avoiding cracking and deformation when thin-wall products are stacked.
Ultra-clean pellets to prevent mold clogging during continuous production
Strict raw material control eliminates black specks, paired with low ash and gel levels. It avoids blockage at nozzles and runners during long-running high-speed injection, cutting mold cleaning downtime and matching fully automatic high-speed production lines.
Low haze & odor-free, fully compliant with food contact regulations
Equipped with premium thermal stabilizers, the resin delivers low haze, high light transmittance and no sharp odor. It fully meets GB 4806 standards for food contact, suitable for disposable food containers, beverage cups and other food packaging; it can also act as a transparent carrier for modified formulations.
Main Application Fields
Disposable Food Packaging: Milk tea cups, fast food containers, transparent beverage containers, thin-wall fresh-keeping boxes, small food storage bowls
Daily Transparent Injection Parts: Small plastic storage boxes, transparent water cups, thin-wall plastic daily storage components
Modified Filling Substrates: Transparent filled modified PP, food-grade masterbatch carriers
Lightweight Thin-Wall Industrial Parts: Small transparent plastic housings, disposable packaging components
Processing & Storage Guidelines
Processing Parameters
Barrel Temperature: 210–240°CNozzle Temperature: 220–250°CMold Temperature: 40–70°CProduct Wall Thickness: 0.3–2 mmNote: This grade is developed specifically for high-speed thin-wall injection molding. Adjust heating parameters according to actual machine conditions to prevent thermal degradation caused by overheating.Drying Guidance: Pellets stored under normal conditions require no pre-drying. If pellets absorb moisture, dry at 60–70°C for 1 hour and cool fully to room temperature before feeding.
Storage Requirements
Store pellets in cool, dry and well-ventilated warehouses. Keep away from direct sunlight, open flames and odorous goods to avoid moisture absorption and odor cross-contamination. Pallet stacking height shall not exceed 5 layers. The shelf life is 2 years under standard storage conditions.

Frequently Asked Questions
Q1: What core processing strengths does high-flow Ningmei 1040TE have?A: With a stable MFR of 58–62 g/10min, 1040TE delivers outstanding melt fluidity. It enables fast full filling of 0.3–2 mm ultra-thin food-grade parts, shortens molding cycles and improves overall throughput for high-speed injection equipment.
Q2: What surface performance can 1040TE achieve for transparent thin-wall food products?A: Made from ultra-clean, speck-free pellets, the resin produces smooth, odorless transparent parts with low haze and high light transmittance, meeting strict appearance standards for high-end food packaging.
Q3: Do high-flow PP grades suffer from insufficient rigidity? Does 1040TE have this issue?A: No. Ethylene modification fixes the softness defect common to ordinary high-flow PP. It combines ultra-high fluidity with high rigidity and stable dimensional performance, effectively preventing warpage and stacking deformation of thin-wall finished goods.
Q4: Can 1040TE support long-term continuous mass production?A: Yes. Low ash, low gel content and excellent thermal stability reduce carbon buildup and nozzle blockage during prolonged high-speed molding, minimizing machine downtime and enabling 24-hour non-stop mass production.
Q5: What advantages does 1040TE hold over conventional thin-wall food-grade PP?A: Produced via Novolen gas-phase technology, 1040TE features steady MFR and consistent batch quality with a wide processing window. It integrates high flow, transparency, rigidity and food safety, allowing direct mass production without modification and delivering superior overall cost performance.
