2025 원자재부터 완제품까지: 빵 봉지 공장의 360° 품질 관리 프로세스 공개​

갓 구운 빵을 집으면, 빵봉투는 처음이야 “보호자”—and behind this simple packaging lies a strict quality journey that starts with 원자재에서 to finished products. 우리 공장의 360° 품질 시스템, built around the principle of 원자재에서 to end, 모든 가방의 안전을 보장합니다, 튼튼한, and up to global standards. Let’s break down the key steps of this 원자재에서-to-finished process!​

🌱 1. Raw Material Selection: The Core of “From Raw Materials to Finished” Quality​

Raw materials are the starting line of our 원자재에서-driven quality control—we focus on two main options: food-grade PE 그리고 kraft paper, both screened to meet the highest safety benchmarks.​

For Food-Grade PE (폴리에틸렌):​

✅ Only source from suppliers with FDA & SGS certifications—this is the first checkpoint in our 원자재에서 프로세스 (global food safety standards non-negotiable).​

✅ 3-step inspection before factory entry (a must for 원자재에서 품질):​

1. Check certification docs to confirm compliance with food contact material rules (no shortcuts in 원자재에서 screening).​

2. Laboratory sensory test: No strange smells, discoloration, or impurities (even a tiny black spot = rejection—we don’t compromise on 원자재에서 품질).​

3. Migration test: Soak PE film in simulated food solution (예를 들어, acetic acid for acidic foods) at 40°C for 24h—test for heavy metals/plasticizers (critical for 원자재에서 안전).​

✅ Must meet China’s GB 4806.7-2016 standard (food contact plastics) to move from 원자재에서 stage to production.​

For Kraft Paper (Premium Bread Packaging):​

🌿 Prioritize 100% recycled fibers with FSC certification—eco-friendliness is part of our 원자재에서 criteria (no toxic additives allowed).​

✅ Random sampling tests (key for 원자재에서 consistency):​

1. Basis weight: Minimum 80g/m² (prevents tearing when holding bread—durability starts at 원자재에서).​

2. Moisture content: 8%-12% (too wet = mold; too dry = brittleness—we control this at 원자재에서 stage).​

3. Grease resistance test: Apply edible oil, observe 24h—no seepage allowed (seepage ruins bread texture, so we eliminate this risk at 원자재에서).​
   

🎨 2. Printing Ink Testing: Safe & Beautiful—A Link Between From Raw Materials and Finished​

After passing 원자재에서 checks, the next step is printing—and ink safety is as critical as raw material quality. We follow a “zero-toxic ink” rule to keep the 원자재에서-to-finished chain safe.​

✅ Only use water-based ink (no VOCs = non-toxic, 냄새 없는, no harmful residue; unlike solvent-based inks—this choice aligns with our 원자재에서 안전 표준).​

✅ Pre-use third-party lab tests: Heavy metals (lead, mercury, cadmium) and benzene compounds must be “undetectable”—we treat ink like a raw material in our 원자재에서 mindset.​

✅ Real-time printing inspections (every 30 minutes):​

1. Ink adhesion test: Wrap sample around 500g weight, rub 20x on white paper—no ink transfer (adjust pressure/temp if needed; this ensures the print lasts from 원자재에서 to customer use).​

2. Printing accuracy: Use calipers to check logo-edge distance—tolerance ±0.5mm (avoids misprints hurting brand image; precision matters as much as 원자재에서 품질).​

✅ “Safe distance” rule: Printed area ≥1cm from the bag’s inner surface (for direct bread contact—extends the 원자재에서 safety promise to the final design).​

✅ Extra protection for transparent PE bags: Add a food-grade film between ink and bread (prevents ink migration—another layer of safety in the 원자재에서-to-finished process).​

💪 3. Pressure Resistance Testing: Durable for Real Life—Protecting the From Raw Materials Investment​

The durability of a bread bag depends not just on 원자재에서 품질, but also on how well it holds up in real use. We simulate real scenarios to ensure the 원자재에서 effort doesn’t go to waste.​

✅ Use a computer-controlled pressure tester:​

1. Pick 50 random samples per batch (from different production line parts for fairness—we test the consistency of the 원자재에서-to-production process).​

2. Seal bag openings (simulate full bread), apply gradual pressure:​

• Regular bags (500g-1kg bread): Withstand 200N (≈20kg weight) for 60s—no breaking/leaking (durability that honors 원자재에서 표준).​

• Large bags (2kg+ bread): Withstand 300N (higher strength for heavier loads—built on reliable 원자재에서).​

✅ Dynamic durability test (simulate delivery):​

1. Fill bags with sandbags (same shape/weight as bread—mimics real use of the 원자재에서-made bag).​

2. Put in vibration tester (5Hz frequency, 10mm amplitude) for 2h (mimics truck bumps—tests if the bag stays intact after 원자재에서 그리고 생산).​

3. Check seams for damage/deformation—1 failed sample = batch on hold (fix material/sealing, retest until pass—we don’t let poor production undo 원자재에서 품질).​

🔍 4. Beyond Key Links: Full-Lifecycle Quality—Completing the From Raw Materials to Finished Journey​

Our 360° process doesn’t stop at core steps—we check until the final bag to ensure the 원자재에서-to-finished journey ends with excellence.​

✅ Finished product visual inspection:​

• Use light tables to spot 0.1mm pinholes (tiny holes = freshness loss—we catch this before the 원자재에서-made bag reaches customers).​

• Check for uneven sealing or dirty marks (no flaws allowed in the final product of our 원자재에서 프로세스).​

✅ Freshness retention test:​

• Put a bread slice in the bag, 밀봉하다, store at 25°C for 3 days.​

• Ensure bread stays soft + no mold (tests airtightness/moisture control—proves the 원자재에서 and production work together to keep bread fresh).​
  

❤️ Why This Matters: From Raw Materials to Trust​

Quality control isn’t just procedures—it’s a mindset centered on 원자재에서 to finished excellence. Every bread bag connects bakeries to customers, so its safety and durability (rooted in 원자재에서 품질) directly affect your brand reputation.​
