2025 Від сировини до готової продукції: Розкриття процесу контролю якості на 360° на заводі з виробництва хлібних мішків

Коли береш в руки свіжоспечений коровай, мішок для хліба - його перший “захисник”—and behind this simple packaging lies a strict quality journey that starts with Від сировини to finished products. Наша фабрична система якості 360°, built around the principle of Від сировини to end, забезпечує безпеку кожної сумки, міцний, and up to global standards. Let’s break down the key steps of this Від сировини-to-finished process!​

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

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

For Food-Grade PE (Поліетилен):​

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

✅ 3-step inspection before factory entry (a must for Від сировини якість):​

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

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

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

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

For Kraft Paper (Premium Bread Packaging):​

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

✅ Random sampling tests (key for Від сировини consistency):​

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

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

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

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

After passing Від сировини 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 Від сировини-to-finished chain safe.​

✅ Only use water-based ink (no VOCs = non-toxic, без запаху, no harmful residue; unlike solvent-based inks—this choice aligns with our Від сировини стандарти безпеки).​

✅ 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 Від сировини 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 Від сировини 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 Від сировини якість).​

✅ “Safe distance” rule: Printed area ≥1cm from the bag’s inner surface (for direct bread contact—extends the Від сировини 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 Від сировини-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 Від сировини якість, but also on how well it holds up in real use. We simulate real scenarios to ensure the Від сировини 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 Від сировини-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 Від сировини стандарти).​

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

✅ Dynamic durability test (simulate delivery):​

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

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

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 Від сировини якість).​

🔍 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 Від сировини-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 Від сировини-made bag reaches customers).​

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

✅ Freshness retention test:​

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

• Ensure bread stays soft + no mold (tests airtightness/moisture control—proves the Від сировини 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 Від сировини to finished excellence. Every bread bag connects bakeries to customers, so its safety and durability (rooted in Від сировини якість) directly affect your brand reputation.​
