For light duty, plastic suffices. But against solvents and freight rules, empty metal paint tins win decisively.

3 Drawbacks Of Plastic Paint Containers

Many professionals switching back to empty metal paint tins do so after experiencing catastrophic plastic packaging failures.

Poor Chemical Resistance and Odor Retention

내화학성 is paramount for industrial coatings. Plastic inherently fails here.

Chemical compatibility risks
- Interaction with strong paint solvents
  - Solvent migration softening the plastic walls
  - Gradual material degradation leading to structural failure
- Near-zero barrier protection compared to epoxy-lined metal
Odor retention problems
- VOC absorption deeply into the polymer structure
  - Permanent lingering smells in reused 플라스틱 용기
  - High cross-batch contamination risk
- Increased risk of complete 제품 오염
Why buyers shift to empty metal paint tins
- Metal offers absolute 내화학성
- Zero solvent permeability
- Total freshness and odor control

Brands like FANXUN engineer metal packaging because professionals dealing with thinners and industrial paints demand absolute stability.

Dimensional Instability under Temperature Fluctuations

Plastic reacts violently to 온도 변화.

Thermal response
- 엄청난 열팽창 (expanding 5–10x more than steel)
- Severe shrinkage in cold storage environments
Structural consequences
- Permanent 소성 변형
  - Lid misalignment and pop-offs
  - Micro-seal gaps
- Compromised 컨테이너 무결성
운영에 미치는 영향
- Dangerous pallet stacking instability
- Total loss of leak resistance
- Exponentially higher transport risk

거꾸로, empty metal paint tins maintain rigid 치수 안정성. Metal resists material stress, protecting warehouse loads. FANXUN designs its metal paint cans to hold ISO tolerances despite extreme climate shifts.

Lack of Regulatory Compliance for Aerosol Directives

For hazmat shipping, 규제 준수 is legally binding.

운송 표준
- UN and DOT CFR 49 인증 요구 사항
- Hydrostatic pressure testing thresholds
- Strict ADR industry standards
Aerosol-specific controls
- 필수적인 aerosol directives
- Burst strength validation
- Zero-leakage prevention under crush loads
Legal exposure
- Failed 안전 규정
- Massive fines or rejected international shipments
- Voided insurance policies

Most plastic formats instantly fail pressure-based 법적 요구 사항. This makes empty metal paint tins the default for regulated markets. FANXUN packaging aligns perfectly with global compliance benchmarks.
