2025 От сырья к готовой продукции: Представляем процесс контроля качества на 360° на фабрике по производству хлебных мешков
Когда берешь в руки свежеиспеченный хлеб, мешок с хлебом - его первый “защитник”—and behind this simple packaging lies a strict quality journey that starts with Из сырья to finished products. Система качества 360° нашей фабрики, built around the principle of Из сырья to end, гарантирует сохранность каждой сумки, прочный, and up to global standards. Let’s break down the key steps of this Из сырья-to-finished process!
🌱 1. Raw Material Selection: The Core of “From Raw Materials to Finished” Quality
Raw materials are the starting line of our Из сырья-driven quality control—we focus on two main options: food-grade PE и kraft paper, both screened to meet the highest safety benchmarks.
For Food-Grade PE (Полиэтилен):
✅ Only source from suppliers with FDA & SGS certifications—this is the first checkpoint in our Из сырья процесс (global food safety standards non-negotiable).
✅ 3-step inspection before factory entry (a must for Из сырья качество):
- Check certification docs to confirm compliance with food contact material rules (no shortcuts in Из сырья screening).
- Laboratory sensory test: No strange smells, discoloration, or impurities (even a tiny black spot = rejection—we don’t compromise on Из сырья качество).
- Migration test: Soak PE film in simulated food solution (НАПРИМЕР., acetic acid for acidic foods) at 40°C for 24h—test for heavy metals/plasticizers (critical for Из сырья безопасность).
✅ Must meet China’s GB 4806.7-2016 стандартный (food contact plastics) to move from Из сырья stage to production.
For Kraft Paper (Premium Bread Packaging):
🌿 Prioritize 100% recycled fibers with FSC certification—eco-friendliness is part of our Из сырья criteria (no toxic additives allowed).
✅ Random sampling tests (key for Из сырья consistency):
- Basis weight: Minimum 80g/m² (prevents tearing when holding bread—durability starts at Из сырья).
- Moisture content: 8%-12% (too wet = mold; too dry = brittleness—we control this at Из сырья stage).
- Grease resistance test: Apply edible oil, observe 24h—no seepage allowed (seepage ruins bread texture, so we eliminate this risk at Из сырья).
🎨 2. Printing Ink Testing: Safe & Beautiful—A Link Between From Raw Materials and Finished
After passing Из сырья 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 Из сырья-to-finished chain safe.
✅ Only use water-based ink (no VOCs = non-toxic, без запаха, no harmful residue; unlike solvent-based inks—this choice aligns with our Из сырья safety standards).
✅ 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 Из сырья mindset.
✅ Real-time printing inspections (every 30 minutes):
- 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 Из сырья to customer use).
- Printing accuracy: Use calipers to check logo-edge distance—tolerance ±0.5mm (avoids misprints hurting brand image; precision matters as much as Из сырья качество).
✅ “Safe distance” rule: Printed area ≥1cm from the bag’s inner surface (for direct bread contact—extends the Из сырья 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 Из сырья-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 Из сырья качество, but also on how well it holds up in real use. We simulate real scenarios to ensure the Из сырья effort doesn’t go to waste.
✅ Use a computer-controlled pressure tester:
- Pick 50 random samples per batch (from different production line parts for fairness—we test the consistency of the Из сырья-to-production process).
- 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 Из сырья стандарты).
- Large bags (2kg+ bread): Withstand 300N (higher strength for heavier loads—built on reliable Из сырья).
✅ Dynamic durability test (simulate delivery):
- Fill bags with sandbags (same shape/weight as bread—mimics real use of the Из сырья-made bag).
- Put in vibration tester (5Hz frequency, 10mm amplitude) for 2h (mimics truck bumps—tests if the bag stays intact after Из сырья and production).
- Check seams for damage/deformation—1 failed sample = batch on hold (fix material/sealing, retest until pass—we don’t let poor production undo Из сырья качество).
🔍 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 Из сырья-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 Из сырья-made bag reaches customers).
- Check for uneven sealing or dirty marks (no flaws allowed in the final product of our Из сырья процесс).
✅ Freshness retention test:
- Put a bread slice in the bag, тюлень, store at 25°C for 3 days.
- Ensure bread stays soft + no mold (tests airtightness/moisture control—proves the Из сырья 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 Из сырья to finished excellence. Every bread bag connects bakeries to customers, so its safety and durability (rooted in Из сырья качество) directly affect your brand reputation.
